Mouse Sgip1 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Sgip1 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Sgip1 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Sgip1 gene (NCBI Reference Sequence: NM_144906 ; Ensembl: ENSMUSG00000028524 ) is located on Mouse chromosome 4. 24 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 24 (Transcript: ENSMUST00000080728). 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 Sgip1 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP24-63D7 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: Exon 2 starts from about 0.45% of the coding region. The knockout of Exon 2 will result in frameshift of the gene. The size of intron 1 for 5'-loxP site insertion: 92317 bp, and the size of intron 2 for 3'-loxP site insertion: 7823 bp. The size of effective cKO region: ~564 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(7064bp) | A(28.94% 2044) | C(20.61% 1456) | T(27.31% 1929) | G(23.15% 1635) 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.

Genome Medicine (2015) 7:76 DOI 10.1186/s13073-015-0195-6 METHOD Open Access CSN and CAVA: variant annotation tools for rapid, robust next-generation sequencing analysis in the clinical setting Márton Münz1†, Elise Ruark2†, Anthony Renwick2, Emma Ramsay2, Matthew Clarke2, Shazia Mahamdallie2,3, Victoria Cloke3, Sheila Seal2,3, Ann Strydom2,3, Gerton Lunter1 and Nazneen Rahman2,3,4* Abstract Background: Next-generation sequencing (NGS) offers unprecedented opportunities to expand clinical genomics. It also presents challenges with respect to integration with data from other sequencing methods and historical data. Provision of consistent, clinically applicable variant annotation of NGS data has proved difficult, particularly of indels, an important variant class in clinical genomics. Annotation in relation to a reference genome sequence, the DNA strand of coding transcripts and potential alternative variant representations has not been well addressed. Here we present tools that address these challenges to provide rapid, standardized, clinically appropriate annotation of NGS data in line with existing clinical standards. Methods: We developed a clinical sequencing nomenclature (CSN), a fixed variant annotation consistent with the principles of the Human Genome Variation Society (HGVS) guidelines, optimized for automated variant annotation of NGS data. To deliver high-throughput CSN annotation we created CAVA (Clinical Annotation of VAriants), a fast, lightweight tool designed for easy incorporation into NGS pipelines. CAVA allows transcript specification, appropriately accommodates the strand of a gene transcript and flags variants with alternative annotations to facilitate clinical interpretation and comparison with other datasets. We evaluated CAVA in exome data and a clinical BRCA1/BRCA2 gene testing pipeline.

  • Computational Studies of the Genome Dynamics of Mammalian Transposable Elements and Their Relationships to Genes
    COMPUTATIONAL STUDIES OF THE GENOME DYNAMICS OF MAMMALIAN TRANSPOSABLE ELEMENTS AND THEIR RELATIONSHIPS TO GENES by Ying Zhang M.Sc., Katholieke Universiteit Leuven (BELGIUM), 2004 B.E., Harbin Institute of Technology (CHINA), 1993 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE STUDIES (Genetics) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) May, 2012 © Ying Zhang, 2012 Abstract Sequences derived from transposable elements (TEs) comprise nearly 40 - 50% of the genomic DNA of most mammalian species, including mouse and human. However, what impact they may exert on their hosts is an intriguing question. Originally considered as merely genomic parasites or “selfish DNA”, these mobile elements show their detrimental effects through a variety of mechanisms, from physical DNA disruption to epigenetic regulation. On the other hand, evidence has been mounting to suggest that TEs sometimes may also play important roles by participating in essential biological processes in the host cell. The dual-roles of TE-host interactions make it critical for us to understand the relationship between TEs and the host, which may ultimately help us to better understand both normal cellular functions and disease. This thesis encompasses my three genome-wide computational studies of TE-gene dynamics in mammals. In the first, I identified high levels of TE insertional polymorphisms among inbred mouse strains, and systematically analyzed their distributional features and biological effects, through mining tens of millions of mouse genomic DNA sequences. In the second, I examined the properties of TEs located in introns, and identified key factors, such as the distance to the intron-exon boundary, insertional orientation, and proximity to splice sites, that influence the probability that TEs will be retained in genes.

  • Structural Basis for the Recognition of Two Consecutive Mutually
    www.nature.com/scientificreports OPEN Structural basis for the recognition of two consecutive mutually interacting DPF motifs by the Received: 07 September 2015 Accepted: 10 December 2015 SGIP1 μ homology domain Published: 29 January 2016 Atsushi Shimada1,2, Atsuko Yamaguchi1 & Daisuke Kohda1 FCHo1, FCHo2, and SGIP1 are key regulators of clathrin-mediated endocytosis. Their μ homology domains (μHDs) interact with the C-terminal region of an endocytic scaffold protein, Eps15, containing fifteen Asp-Pro-Phe (DPF) motifs. Here, we show that the high-affinityμ HD-binding site in Eps15 is a region encompassing six consecutive DPF motifs, while the minimal μHD-binding unit is two consecutive DPF motifs. We present the crystal structures of the SGIP1 μHD in complex with peptides containing two DPF motifs. The peptides bind to a novel ligand-binding site of the μHD, which is distinct from those of other distantly related μHD-containing proteins. The two DPF motifs, which adopt three-dimensional structures stabilized by sequence-specific intramotif and intermotif interactions, are extensively recognized by the μHD and are both required for binding. Thus, consecutive and singly scattered DPF motifs play distinct roles in μHD binding. Clathrin-mediated endocytosis (CME) is a process by which eukaryotic cells internalize extracellular molecules. It plays a critical role in numerous physiological phenomena, such as cell surface receptor internalization, nutri- ent uptake, and neurotransmission, and is exploited by viruses and bacteria for their entry into cells1. Many pro- teins involved in CME contain repeated sequence motifs, such as the Asp-Pro-Phe (DPF), Asn-Pro-Phe (NPF), and Asp-Pro-Trp (DPW) motifs2,3.

Species Reactivity: Human Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asn189 of human REPS1 protein. Antibodies are purified by protein A and peptide affinity chromatography. Background REPS1 is a RalBP1-associated EH-homology domain containing protein. The sequence of REPS1 has an EH domain, followed by two proline-rich segments, and a C-terminal coiled-coil domain for binding to RalBP1 (1). The EH domain of REPS1 interacts with the NPF motif of Rab11-FIP2, mediates their colocalization to endosome vesicles, and influences EGFR endocytosis (2). The two proline-rich regions of REPS1 are important for binding to the SH3 domain of GRK/GRB2 and further regulate EGFR downstream signaling. The proline-rich regions of REPS1 have also been shown to interact with the SH3 domain of intersectin1 (ITSN1) and contribute to ITSN1/SGIP1/REPS1 complex formation on clathrin-coated pits (3).
