Our two labs independently reported the initial studies of version 2 this domain, which is encoded almost entirely within a single gene (revision) report report family. The name Neuroblastoma Breakpoint Family (NBPF) was 17 Jul 2018 applied to this gene family when the first identified member of the family was found to be interrupted in an individual with version 1 neuroblastoma. 28 Dec 2017 report report report Prior to this discovery, the Pfam database had termed the domain DUF1220, denoting it as one of many protein domains of unknown f unction. It has been Pfam’s intention to use “DUF” nomenclature to 1.

Bertozzi, Co-Chair Professor David E. Wemmer, Co-Chair Changes in glycosylation have long been appreciated to be part of the cancer phenotype; sialylated glycans are found at elevated levels on many types of cancer and have been implicated in disease progression. However, the specific glycoproteins that contribute to cell surface sialylation are not well characterized, specifically in bona fide human cancer. Metabolic and bioorthogonal labeling methods have previously enabled enrichment and identification of sialoglycoproteins from cultured cells and model organisms. The goal of this work was to develop technologies that can be used for detecting changes in glycoproteins in clinical models of human cancer.

DUF1220-Domain Copy Number Implicated in Human Brain-Size Pathology and Evolution
ARTICLE DUF1220-Domain Copy Number Implicated in Human Brain-Size Pathology and Evolution Laura J. Dumas,1 Majesta S. O’Bleness,1 Jonathan M. Davis,1,2 C. Michael Dickens,1 Nathan Anderson,1 J.G. Keeney,1 Jay Jackson,1 Megan Sikela,1 Armin Raznahan,3 Jay Giedd,3 Judith Rapoport,3 Sandesh S.C. Nagamani,4 Ayelet Erez,4 Nicola Brunetti-Pierri,5,6 Rachel Sugalski,7 James R. Lupski,4 Tasha Fingerlin,2 Sau Wai Cheung,4 and James M. Sikela1,* DUF1220 domains show the largest human-lineage-specific increase in copy number of any protein-coding region in the human genome and map primarily to 1q21, where deletions and reciprocal duplications have been associated with microcephaly and macro- cephaly, respectively. Given these findings and the high correlation between DUF1220 copy number and brain size across primate line- À ages (R2 ¼ 0.98; p ¼ 1.8 3 10 6), DUF1220 sequences represent plausible candidates for underlying 1q21-associated brain-size pathol- ogies. To investigate this possibility, we used specialized bioinformatics tools developed for scoring highly duplicated DUF1220 sequences to implement targeted 1q21 array comparative genomic hybridization on individuals (n ¼ 42) with 1q21-associated micro- cephaly and macrocephaly. We show that of all the 1q21 genes examined (n ¼ 53), DUF1220 copy number shows the strongest asso- ciation with brain size among individuals with 1q21-associated microcephaly, particularly with respect to the three evolutionarily conserved DUF1220 clades CON1(p ¼ 0.0079), CON2 (p ¼ 0.0134), and CON3 (p ¼ 0.0116). Interestingly, all 1q21 DUF1220-encoding genes belonging to the NBPF family show significant correlations with frontal-occipital-circumference Z scores in the deletion group.

Biochemical studies 20 suggest that Spc110 facilitates higher-order -tubulin complex assembly (Kollman et al., 21 2010). Nevertheless the molecular basis for this activity and the regulation are unclear. 22 Here we show that Spc110 phosphorylated by Mps1 and Cdk1 activates -TuSC 23 oligomerization and MT nucleation in a cell cycle dependent manner. Interaction between 24 the N-terminus of the -TuSC subunit Spc98 and Spc110 is important for this activity. 25 Besides the conserved CM1 motif in -TuCRs (Sawin et al., 2004), a second motif that we 26 named Spc110/Pcp1 motif (SPM) is also important for MT nucleation. The activating Mps1 27 and Cdk1 sites lie between SPM and CM1 motifs.

In striated (i.e., skeletal and cardiac) muscle cells, the nuclear envelope acts as the dominant microtubule-organizing center (MTOC) and the function of the centrosome—the canonical MTOC of mammalian cells—is attenuated, a common feature of differentiated cell types. We summarize the mechanisms known to underlie MTOC formation at the nuclear envelope, discuss the significance of the nuclear envelope MTOC for muscle function and cell cycle progression, and outline potential mechanisms of centrosome attenuation. Keywords: centrosome; MTOC; non-centrosomal MTOC; skeletal muscle; cardiomyocytes; cell cycle; microtubules 1. Introduction: Non-Centrosomal Microtubule-Organizing Centers—A Hallmark of Differentiation Microtubules are an integral part of the cytoskeleton, playing important roles in cellular processes such as intracellular trafficking, cell division, and maintenance of cellular architecture including shape, polarity, and organelle positioning. In proliferating animal cells, the majority of microtubules are organized by an organelle termed the centrosome, which is therefore labeled the dominant microtubule-organizing center (MTOC).

Esta región es altamente repetitiva y por ello requiere tecnologías de secuenciación basadas en long reads para poder genotipar a sus pacientes de forma precisa. Además, 1q21.1 comprende múltiples duplicaciones segmentarias, tales como los dominios Olduvai, asociados con macro- y microcefalia. El primer objetivo de este estudio es diseñar un pipeline de detección de variantes estructurales a partir de secuenciación con long reads. El proyecto incluye la simulación de genomas con diversas variantes estructurales y la simulación de reads de secuenciación que permitan validar la aplicación de este pipeline. El segundo objetivo es analizar la filogenia de los dominios Olduvai durante la evolución.

Karajannis 21 1234567890():,; Pineoblastoma is a rare and highly aggressive brain cancer of childhood, histologically belonging to the spectrum of primitive neuroectodermal tumors. Patients with germline mutations in DICER1, a ribonuclease involved in microRNA processing, have increased risk of pineoblastoma, but genetic drivers of sporadic pineoblastoma remain unknown. Here, we analyzed pediatric and adult pineoblastoma samples (n = 23) using a combination of genome- wide DNA methylation profiling and whole-exome sequencing or whole-genome sequencing. Pediatric and adult pineoblastomas showed distinct methylation profiles, the latter clustering with lower-grade pineal tumors and normal pineal gland. Recurrent variants were found in genes involved in PKA- and NF-κB signaling, as well as in chromatin remodeling genes. We identified recurrent homozygous deletions of DROSHA, acting upstream of DICER1 in micro- RNA processing, and a novel microduplication involving chromosomal region 1q21 containing PDE4DIP (myomegalin), comprising the ancient DUF1220 protein domain.
