Mouse Trim32 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Trim32 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Trim32 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Trim32 gene (NCBI Reference Sequence: NM_053084 ; Ensembl: ENSMUSG00000051675 ) is located on Mouse chromosome 4. 2 exons are identified, with the ATG start codon in exon 2 and the TAA stop codon in exon 2 (Transcript: ENSMUST00000050850). Exon 2 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Trim32 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-234I22 as template. Cas9, gRNA and targeting vector will be co-injected into fertilized eggs for cKO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Mice homozygous for a gene trapped allele exhibit mild myopathy with sarcotubular myopathy, decreased fertility, and decreased axon diameter. Mice homozygous for a knock-out allele exhibit impaired adult muscle regeneration and myopathy. Exon 2 covers 100.0% of the coding region. Start codon is in exon 2, and stop codon is in exon 2. The size of effective cKO region: ~2317 bp. The cKO region does not have any other known gene.

Tandem repeats are found in the dot plot matrix. It may be difficult to construct this targeting vector. Overview of the GC Content Distribution Window size: 300 bp Sequence 12 Summary: Full Length(7965bp) | A(25.26% 2012) | C(22.16% 1765) | T(28.71% 2287) | G(23.87% 1901) Note: The sequence of homologous arms and cKO region is analyzed to determine the GC content. No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.

We also performed extensive searches using the TblastN algorithm through all publicly available microbial genome databases including those attached to the NCBI BLAST server for bacterial genomes (http://www.ncbi.nlm.nih.gov/sutils/genom_table.cgi?), as well as several additional microbial genome databases – Microbial Genomics at the DOE Joint Genome Institute (http://genome.jgi-psf.org/mic_home.html), the Rumenomics database at TIGR/JCVI (http://tigrblast.tigr.org/rumenomics/index.cgi) and Bacterial Genomes at the Sanger Centre (http://www.sanger.ac.uk/Projects/Microbes/). Once a putative cohesin or dockerin-encoding gene product was identified, gene-walking techniques were employed to analyze and locate possible cellulosome-like gene clusters.

Abstract Background: The Asp-box is a short sequence and structure motif that folds as a well-defined β- hairpin. It is present in different folds, but occurs most prominently as repeats in β-propellers. Asp- box β-propellers are known to be characteristically irregular and to occur in many medically important proteins, most of which are glycosidase enzymes, but they are otherwise not well characterized and are only rarely treated as a distinct β-propeller family. We have analyzed the sequence, structure, function and occurrence of the Asp-box and s-Asp-box -a related shorter variant, and provide a comprehensive classification and computational analysis of the Asp-box β- propeller family.

  • Protein Family Expansions and Biological Complexity
    Protein Family Expansions and Biological Complexity Christine Vogel1,2*, Cyrus Chothia1 1 Medical Research Council Laboratory of Molecular Biology, Cambridge, United Kingdom, 2 Institute for Cellular and Molecular Biology, University of Texas at Austin, Austin, Texas, United States of America During the course of evolution, new proteins are produced very largely as the result of gene duplication, divergence and, in many cases, combination. This means that proteins or protein domains belong to families or, in cases where their relationships can only be recognised on the basis of structure, superfamilies whose members descended from a common ancestor. The size of superfamilies can vary greatly. Also, during the course of evolution organisms of increasing complexity have arisen. In this paper we determine the identity of those superfamilies whose relative sizes in different organisms are highly correlated to the complexity of the organisms. As a measure of the complexity of 38 uni- and multicellular eukaryotes we took the number of different cell types of which they are composed. Of 1,219 superfamilies, there are 194 whose sizes in the 38 organisms are strongly correlated with the number of cell types in the organisms. We give outline descriptions of these superfamilies. Half are involved in extracellular processes or regulation and smaller proportions in other types of activity. Half of all superfamilies have no significant correlation with complexity. We also determined whether the expansions of large superfamilies correlate with each other. We found three large clusters of correlated expansions: one involves expansions in both vertebrates and plants, one just in vertebrates, and one just in plants.

  • The E3 Ligase TRIM32 Is an Effector of the RAS Family Gtpase RAP2
    The E3 Ligase TRIM32 is an effector of the RAS family GTPase RAP2 Berna Demiray A thesis submitted towards the degree of Doctor of Philosophy Cancer Institute University College London 2014 Declaration I, Berna Demiray, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated. London, 2014 The E3 Ligase TRIM32 is an Effector of the RAS family GTPase RAP2 Classical RAS oncogenes are mutated in approximately 30% of human tumours and RAP proteins are closely related to classical RAS proteins. RAP1 has an identical effector domain to RAS whereas RAP2 differs by one amino acid. RAP2 not only shares effectors with other classical RAS family members, but it also has its own specific effectors that do not bind to RAP1 or classical RAS family proteins. Thus, although closely related, RAP2 performs distinct functions, although these have been poorly characterised. Using RAP2 as bait in Tandem Affinity Purifications, we have identified several RAP2 interacting proteins including TRIM32; a protein implicated in diverse pathological processes such as Limb-Girdle Muscular Dystrophy (LGMD2H), and Bardet-Biedl syndrome (BBS). TRIM32 was shown to interact specifically with RAP2 in an activation- and effector domain-dependent manner; demonstrating stronger interaction with the RAP2 V12 mutant than the wild-type RAP2 and defective binding to the effector mutant RAP2 V12A38. The interaction was mapped to the C-terminus of TRIM32 (containing the NHL domains) while mutations found in LGMD2H (R394H, D487N, ∆588) were found to disrupt binding to RAP2. The TRIM32 P130S mutant linked to BBS did not affect binding to RAP2, suggesting that the RAP2-TRIM32 interaction may be functionally involved in LGMD2H.
