Characterisation of the Α1b-Adrenoceptor by Modeling, Dynamics and Virtual Screening Kapil Jain B.Pharm, M.S.(Pharm.)
Characterisation of the α1B-Adrenoceptor by Modeling, Dynamics and Virtual Screening Kapil Jain B.Pharm, M.S.(Pharm.) A Thesis submitted for the degree of Master of Philosophy at The University of Queensland in 2018 Institute for Molecular Bioscience 0 Abstract G protein-coupled receptors (GPCRs) are the largest druggable class of proteins yet relatively little is known about the mechanism by which agonist binding induces the conformational changes necessary for G protein activation and intracellular signaling. Recently, the Kobilka group has shown that agonists, neutral antagonists and inverse agonists stabilise distinct extracellular surface (ECS) conformations of the β2-adrenergic receptor (AR) opening up new possibilities for allosteric drug targeting at GPCRs. The goal of this project is to extend these studies to define how the ECS conformation of the α1B-AR changes during agonist binding and develop an understanding of ligand entry and exit mechanisms that may help in the design of specific ligands with higher selectivity, efficacy and longer duration of action. Two parallel approaches were initiated to identify likely functional residues. The role of residues lining the primary binding site were predicted by online web server (Q-Site Finder) while secondary binding sites residues were predicted from molecular dynamics (MD) simulations. Predicted functionally significant residues were mutated and their function was established using FLIPR, radioligand and saturation binding assays. Despite the α1B-AR being pursued as a drug target for over last few decades, few specific agonists and antagonists are known to date. In an attempt to address this gap, we pursued ligand-based approach to find potential new leads. -

Symptoms can be complex and expansive, often leading to symptoms representing other disorders in addition to the primary reason for treatment. In particular mental health disorders fall prey to this situation. Targeting treatment can be difficult due to the implication of receptors in more than one disorder, and more than one receptor in a single disorder. In the instance of GPCRs, receptors such as the serotonin receptors (and in particular the 5-HT2A for the interest of this research) belong to a large family of receptors, the GPCR Class A super family. -

Abstract: G-protein-coupled receptors (GPCRs) comprise a large protein superfamily divided into six classes, rhodopsin-like (A), secretin receptor family (B), metabotropic glutamate (C), fungal mating pheromone receptors (D), cyclic AMP receptors (E) and frizzled (F). Until recently, GPCRs signaling was thought to emanate exclusively from the plasma membrane as a response to extracellular stimuli but several studies have challenged this view demonstrating that GPCRs can be present in intracellular localizations, including in the nuclei. A renewed interest in GPCR receptors’ superfamily emerged and intensive research occurred over recent decades, particularly regarding class A GPCRs, but some class B and C have also been explored. Nuclear GPCRs proved to be functional and capable of triggering identical and/or distinct signaling pathways associated with their counterparts on the cell surface bringing new insights into the relevance of nuclear GPCRs and highlighting the Citation: Gonçalves-Monteiro, S.; nucleus as an autonomous signaling organelle (triggered by GPCRs). -

Origi- nally, an individual GPCR was thought to signal through one G protein family, comprising cognate G proteins Keywords: that mediate canonical receptor signaling. However, several deviations from canonical signaling pathways for GPCR GPCRs have been described. It is now clear that GPCRs can engage with multiple G proteins and the line between Gprotein cognate and non-cognate signaling is increasingly blurred. Furthermore, GPCRs couple to non-G protein trans- β-arrestin ducers, including β-arrestins or other scaffold proteins, to initiate additional signaling cascades. Selectivity Biased Signaling Receptor/transducer selectivity is dictated by agonist-induced receptor conformations as well as by collateral fac- Therapeutic Potential tors. In particular, ligands stabilize distinct receptor conformations to preferentially activate certain pathways, designated ‘biased signaling’. In this regard, receptor sequence alignment and mutagenesis have helped to iden- tify key receptor domains for receptor/transducer specificity. -

Communicating Biochemistry: Meetings and Events
© The Authors. Volume compilation © 2011 Portland Press Limited Chapter 3 Communicating Biochemistry: Meetings and Events Ian Dransfield and Brian Beechey Scientific conferences organized by the Biochemical Society represent a key facet of activity throughout the Society’s history and remain central to the present mission of promoting the advancement of molecular biosciences. Importantly, scientific conferences are an important means of communicating research findings, establishing collaborations and, critically, a means of cementing the community of biochemical scientists together. However, in the past 25 years, we have seen major changes to the way in which science is communicated and also in the way that scientists interact and establish collabo- rations. For example, the ability to show videos, “fly through” molecular structures or show time-lapse or real-time movies of molecular events within cells has had a very positive impact on conveying difficult concepts in presentations. However, increased pressures on researchers to obtain/maintain funding can mean that there is a general reluctance to present novel, unpublished data. In addition, the development of email and electronic access to scientific journals has dramatically altered the potential for communi- cation and accessibility of information, perhaps reducing the necessity of attending meetings to make new contacts and to hear exciting new science. The Biochemical Society has responded to these challenges by progressive development of the meetings format to better match the -
