Mouse Vars2 Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Vars2 Knockout Project (CRISPR/Cas9) Objective: To create a Vars2 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Vars2 gene (NCBI Reference Sequence: NM_175137 ; Ensembl: ENSMUSG00000038838 ) is located on Mouse chromosome 17. 29 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 29 (Transcript: ENSMUST00000043674). Exon 7~25 will be selected as target site. Cas9 and gRNA will be co-injected into fertilized eggs for KO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Exon 7 starts from about 21.13% of the coding region. Exon 7~25 covers 63.05% of the coding region. The size of effective KO region: ~6721 bp. The KO region does not have any other known gene.

    Anti-VARS (aa 994-1102) polyclonal antibody (DPAB-DC3179) This product is for research use only and is not intended for diagnostic use. PRODUCT INFORMATION Antigen Description Aminoacyl-tRNA synthetases catalyze the aminoacylation of tRNA by their cognate amino acid. Because of their central role in linking amino acids with nucleotide triplets contained in tRNAs, aminoacyl-tRNA synthetases are thought to be among the first proteins that appeared in evolution. The protein encoded by this gene belongs to class-I aminoacyl-tRNA synthetase family and is located in the class III region of the major histocompatibility complex.

Heemskerk1,9* Novel platelet and megakaryocyte transcriptome analysis allows prediction of the full or theoretical proteome of a representative human platelet. Here, we integrated the established platelet proteomes from six cohorts of healthy subjects, encompassing 5.2 k proteins, with two novel genome‑wide transcriptomes (57.8 k mRNAs). For 14.8 k protein‑coding transcripts, we assigned the proteins to 21 UniProt‑based classes, based on their preferential intracellular localization and presumed function. This classifed transcriptome‑proteome profle of platelets revealed: (i) Absence of 37.2 k genome‑ wide transcripts. (ii) High quantitative similarity of platelet and megakaryocyte transcriptomes (R = 0.75) for 14.8 k protein‑coding genes, but not for 3.8 k RNA genes or 1.9 k pseudogenes (R = 0.43–0.54), suggesting redistribution of mRNAs upon platelet shedding from megakaryocytes. (iii) Copy numbers of 3.5 k proteins that were restricted in size by the corresponding transcript levels (iv) Near complete coverage of identifed proteins in the relevant transcriptome (log2fpkm > 0.20) except for plasma‑derived secretory proteins, pointing to adhesion and uptake of such proteins. (v) Underrepresentation in the identifed proteome of nuclear‑related, membrane and signaling proteins, as well proteins with low‑level transcripts.

  • Physiological and Molecular Consequences of Large Y Chromosome Long Arm Deletions in Mice
    Physiological and Molecular Consequences of Large Y Chromosome Long Arm Deletions in Mice Emma Elizabeth Philippa Johnson MRes Emmanuel College Department of Pathology University of Cambridge September 2017 This dissertation is submitted for the degree of Doctor of Philosophy. This dissertation is submitted to the University of Cambridge in accordance with requirements of the degree of Doctor of Philosophy in the School of the Biological Sciences. Page 1 of 331 Page 2 of 331 Physiological and Molecular Consequences of Large Y Chromosome Long Arm Deletions in Mice Emma Elizabeth Philippa Johnson Summary The mammalian Y chromosome contains genes important for male sexual maturity and reproduction. The mouse Y chromosome long arm harbours a number of multi-copy genes whose absence or reduced representation has been linked to sperm defects and offspring sex ratio distortion in favour of females. Understanding the biological mechanisms of sex ratio distortion and related sperm aberrations could not only result in benefits for fertility research, but also in the development of methods for large scale animal breeding pre-implantation sex selection. The distortion has been linked to an intragenomic conflict between the X and Y chromosomes that impacts spermiogenesis. Since the proportion of X- and Y-bearing sperm does not differ in affected animals, and there is no selective destruction of male embryos post-fertilisation, a functional difference must exist between the X- and Y-bearing sperm. This thesis describes the investigation into the physiological and molecular mechanisms of a large Y-chromosome long arm deletion in the mouse model MF1XYRIIIqdel. The examination of physiological characteristics revealed a distinct sperm morphology within the deletion model.

When cells are stimulated with interferon y, two structurally similar proteasome (3-type subunits, designated MHC-encoded subunits, low molecular mass polypeptide MECL1 and Z, whose expression is regulated reciprocally by (LMP) 2 and LMP7, and the MECL1 subunit encoded outside IFN-y. When cells are stimulated with IFN--y, the MECL1 the MHC are incorporated into the proteasomal complex, subunit is thought to be incorporated into the proteasome by presumably by displacing the housekeeping subunits desig- displacing the housekeeping Z subunit.

  • A Novel Compound Heterozygous Mutation in VARS2 in a Newborn
    Ma et al. BMC Medical Genetics (2018) 19:202 https://doi.org/10.1186/s12881-018-0689-3 CASE REPORT Open Access A novel compound heterozygous mutation in VARS2 in a newborn with mitochondrial cardiomyopathy: a case report of a Chinese family Keze Ma1,2†, Mingyu Xie1,2†, Xiaoguang He1,2, Guojun Liu1,2, Xiaomei Lu2, Qi Peng2, Baimao Zhong1,2* and Ning Li1,2* Abstract Background: Genetic defects in the mitochondrial aminoacyl-tRNA synthetase are important causes of mitochondrial disorders. VARS2 is one of the genes encoding aminoacyl-tRNA synthetases. Recently, an increasing number of pathogenic variants of VARS2 have been reported. Case presentation: We report the novel compound heterozygous pathogenic VARS2 mutations c.643 C > T (p. His215Tyr) and c.1354 A > G (p. Met452Val) in a female infant who presented with poor sucking at birth, poor activity, hyporeflexia, hypertonia, persistent pulmonary hypertension of newborn (PPHN), metabolic acidosis, severe lactic acidosis, expansion and hypertrophic cardiomyopathy. These heterozygous mutations were carried individually by the proband’s parents and elder sister; the two mutations segregated in the family and were the cause of the disease in theproband.Thec.643C>T(p. His215Tyr) mutation was not described in the ExaC, GNomAD and 1000 Genomes Project databases, and the frequency of c.1354 A > G (p. Met452Val) was < 0.001 in these gene databases.The two mutated amino acids were located in a highly conserved region of the VARS2 protein that is important for its interaction with the cognate tRNA. The two missense mutations were predicted by online tools to be damaging and deleterious.
