The Classification of Esterases: an Important Gene Family Involved in Insecticide Resistance - a Review
Mem Inst Oswaldo Cruz, Rio de Janeiro, Vol. 107(4): 437-449, June 2012 437 The classification of esterases: an important gene family involved in insecticide resistance - A Review Isabela Reis Montella1,2, Renata Schama1,2,3/+, Denise Valle1,2,3 1Laboratório de Fisiologia e Controle de Artrópodes Vetores, Instituto Oswaldo Cruz-Fiocruz, Av. Brasil 4365, 21040-900 Rio de Janeiro, RJ, Brasil 2Instituto de Biologia do Exército, Rio de Janeiro, RJ, Brasil 3Instituto Nacional de Ciência e Tecnologia em Entomologia Molecular, Rio de Janeiro, RJ, Brasil The use of chemical insecticides continues to play a major role in the control of disease vector populations, which is leading to the global dissemination of insecticide resistance. A greater capacity to detoxify insecticides, due to an increase in the expression or activity of three major enzyme families, also known as metabolic resistance, is one major resistance mechanisms. The esterase family of enzymes hydrolyse ester bonds, which are present in a wide range of insecticides; therefore, these enzymes may be involved in resistance to the main chemicals employed in control programs. Historically, insecticide resistance has driven research on insect esterases and schemes for their classification. Currently, several different nomenclatures are used to describe the esterases of distinct species and a universal standard classification does not exist. The esterase gene family appears to be rapidly evolving and each insect species has a unique complement of detoxification genes with only a few orthologues across species. The examples listed in this review cover different aspects of their biochemical nature. However, they do not appear to contribute to reliably distinguish among the different resistance mechanisms.

Interaction of Acetylcholinesterase with Neurexin-1Β Regulates
Xiang et al. Molecular Brain 2014, 7:15 http://www.molecularbrain.com/content/7/1/15 RESEARCH Open Access Interaction of Acetylcholinesterase with Neurexin-1β regulates Glutamatergic Synaptic stability in Hippocampal neurons Yun-Yan Xiang1,2†, Haiheng Dong3†, Burton B Yang4, John F MacDonald1,2 and Wei-Yang Lu1,2,3,5* Abstract Background: Excess expression of acetylcholinesterase (AChE) in the cortex and hippocampus causes a decrease in the number of glutamatergic synapses and alters the expression of neurexin and neuroligin, trans-synaptic proteins that control synaptic stability. The molecular sequence and three-dimensional structure of AChE are homologous to the corresponding aspects of the ectodomain of neuroligin. This study investigated whether excess AChE interacts physically with neurexin to destabilize glutamatergic synapses. Results: The results showed that AChE clusters colocalized with neurexin assemblies in the neurites of hippocampal neurons and that AChE co-immunoprecipitated with neurexin from the lysate of these neurons. Moreover, when expressed in human embryonic kidney 293 cells, N-glycosylated AChE co-immunoprecipitated with non-O–glycosylated neurexin-1β,withN-glycosylation of the AChE being required for this co-precipitation to occur. Increasing extracellular AChE decreased the association of neurexin with neuroligin and inhibited neuroligin-induced synaptogenesis. The number and activity of excitatory synapses in cultured hippocampal neurons were reduced by extracellular catalytically inactive AChE. Conclusions: Excessive glycosylated AChE could competitively disrupt a subset of the neurexin–neuroligin junctions consequently impairing the integrity of glutamatergic synapses. This might serve a molecular mechanism of excessive AChE induced neurodegeneration. Keywords: Protein interaction, Glycosylation, Neurodegeneration, Synaptic apoptosis Introduction globular monomers and dimers of AChE-S.

Gephyrin: a Central Gabaergic Synapse Organizer
OPEN Experimental & Molecular Medicine (2015) 47, e158; doi:10.1038/emm.2015.5 & 2015 KSBMB. All rights reserved 2092-6413/15 www.nature.com/emm REVIEW Gephyrin: a central GABAergic synapse organizer Gayoung Choii1 and Jaewon Ko1,2 Gephyrin is a central element that anchors, clusters and stabilizes glycine and γ-aminobutyric acid type A receptors at inhibitory synapses of the mammalian brain. It self-assembles into a hexagonal lattice and interacts with various inhibitory synaptic proteins. Intriguingly, the clustering of gephyrin, which is regulated by multiple posttranslational modifications, is critical for inhibitory synapse formation and function. In this review, we summarize the basic properties of gephyrin and describe recent findings regarding its roles in inhibitory synapse formation, function and plasticity. We will also discuss the implications for the pathophysiology of brain disorders and raise the remaining open questions in this field.

Mutations in Neuroligin-3 in Male Mice Impact Behavioral Flexibility but Not Relational Memory in a Touchscreen Test of Visual Transitive Inference Rebecca H
Norris et al. Molecular Autism (2019) 10:42 https://doi.org/10.1186/s13229-019-0292-2 RESEARCH Open Access Mutations in neuroligin-3 in male mice impact behavioral flexibility but not relational memory in a touchscreen test of visual transitive inference Rebecca H. C. Norris1, Leonid Churilov2,3, Anthony J. Hannan1,4,5 and Jess Nithianantharajah1,4* Abstract Cognitive dysfunction including disrupted behavioral flexibility is central to neurodevelopmental disorders such as Autism Spectrum Disorder (ASD). A cognitive measure that assesses relational memory, and the ability to flexibly assimilate and transfer learned information is transitive inference. Transitive inference is highly conserved across vertebrates and disrupted in cognitive disorders. Here, we examined how mutations in the synaptic cell-adhesion molecule neuroligin-3 (Nlgn3) that have been documented in ASD impact relational memory and behavioral flexibility. We first refined a rodent touchscreen assay to measure visual transitive inference, then assessed two mouse models of Nlgn3 dysfunction (Nlgn3−/y and Nlgn3R451C). Deep analysis of touchscreen behavioral data at a trial level established we could measure trajectories in flexible responding and changes in processing speed as cognitive load increased. We show that gene mutations in Nlgn3 do not disrupt relational memory, but significantly impact flexible responding. Our study presents the first analysis of reaction times in a rodent transitive inference test, highlighting response latencies from the touchscreen system are useful indicators of processing demands or decision-making processes. These findings expand our understanding of how dysfunction of key components of synaptic signaling complexes impact distinct cognitive processes disrupted in neurodevelopmental disorders, and advance our approaches for dissecting rodent behavioral assays to provide greater insights into clinically relevant cognitive symptoms.

Current address: Department of Psychosis studies, Institute of Psychiatry, Psychology and Neuroscience, King’s College London, London SE5 8AF, United Kingdom * Corresponding author Abstract The trans-synaptic adhesion molecule Neuroligin-2 (NL2) is essential for the development and function of inhibitory synapses. NL2 recruits the postsynaptic scaffold protein gephyrin, which in turn stabilises GABAA receptors (GABAARs) in the postsynaptic domain. Dynamic regulation of synaptic GABAAR concentration is crucial for inhibitory neurotransmission efficacy. Changes in synaptic levels of NL2 contribute to regulating GABAAR synaptic concentration, however the mechanisms that control NL2 synaptic stabilisation are mostly unknown. Here, by combining biochemistry, imaging, single particle tracking and electrophysiology, we identify a key role for cAMP-dependent protein kinase (PKA) in synaptic stabilisation of NL2. We show that PKA- mediated phosphorylation of NL2 at S714 causes its dispersal from the synapse and reduces NL2 surface levels, leading to a loss of synaptic GABAARs. Conversely, enhanced stability of NL2 at synapses through abolishing phosphorylation leads to increased inhibitory signalling.

Sex-Linked Neuroligins and Their Roles at Synapses A
SEX-LINKED NEUROLIGINS AND THEIR ROLES AT SYNAPSES A Dissertation submitted to the Faculty of the Graduate School of Arts and Sciences of Georgetown University in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Pharmacology By Thien Anh Nguyen, B.S. Washington, D.C. March 3, 2020 Copyright 2020 by Thien A. Nguyen All Rights Reserved ii SEX-LINKED NEUROLIGINS AND THEIR ROLES AT SYNAPSES Thien A Nguyen, B.S. Thesis Advisor: Katherine W. Roche, PhD ABSTRACT Autism spectrum disorder (ASD) is a neurodevelopmental disorder that results in social- communication impairments, restricted and repetitive behaviors, and is more prevalent in males. Although the underlying etiology of ASD is generally unknown, a cell adhesion molecule, Neuroligin 4X (NLGN4X) located on the X chromosome, has been specifically linked with this disorder. The male-specific NLGN4Y, the NLGN4X homolog, is thought to be functionally redundant, but this assumption has not been experimentally tested. In this dissertation, we report NLGN4X and NLGN4Y are functionally different. NLGN4Y does not effectively traffic to the surface or induce synapses. We show that a critical amino acid difference in the extracellular domain (ECD) between NLGN4X (P93) and NLGN4Y (S93) leads to this differential function. In addition, we show that NLGN4X is robustly phosphorylated by protein kinase A and protein kinase C, whereas NLGN4Y cannot. The differential phosphorylation is due to one amino acid difference in the intracellular domain (ICD) between NLGN4X (R710) and NLGN4Y (H710). Together, we demonstrate that NLGN4X and NLGN4Y do not share the same function. Interestingly, many ASD-associated variants have been identified in NLGN4X in the region surrounding P93, and there is a decrease in normal population variation in this region.

Abstract Building arborisations of the right size and shape is fundamental for neural network function. Live imaging studies in vertebrate brains strongly suggest that nascent synapses are critical for branch growth during the development of axonal and dendritic arborisations. The molecular mechanisms underlying such ‘synaptotropic’ events are largely unknown. Here we present a novel system in Drosophila for studying the development of complex axonal arborisations live, in vivo during metamorphosis. In these growing axonal arborisations we see a relationship between the punctate localisations of presynaptic components and branch dynamics that is very similar to synaptotropic growth described in fish and frogs.
