Mouse Strn4 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Strn4 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Strn4 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Strn4 gene (NCBI Reference Sequence: NM_133789 ; Ensembl: ENSMUSG00000030374 ) is located on Mouse chromosome 7. 18 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 17 (Transcript: ENSMUST00000019220). Exon 2~3 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Strn4 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-316H6 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 12.41% of the coding region. The knockout of Exon 2~3 will result in frameshift of the gene. The size of intron 1 for 5'-loxP site insertion: 5861 bp, and the size of intron 3 for 3'-loxP site insertion: 1059 bp. The size of effective cKO region: ~1084 bp. The cKO region does not have any other known gene.

No significant tandem repeat is found in the dot plot matrix. So this region is suitable for PCR screening or sequencing analysis.

No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.

  • The MAP4K4-STRIPAK Complex Promotes Growth and Tissue Invasion In

We find that STRN3 13 and STRN4 scaffold subunits of the STRIPAK complex interact with MAP4K4 for pathway regulation in 14 medulloblastoma. Disruption of the MAP4K4-STRIPAK complex impairs growth factor-induced 15 migration and tissue invasion and stalls YAP/TAZ target gene expression and oncogenic growth. The 16 migration promoting functions of the MAP4K4-STRIPAK complex involve the activation of novel PKCs 17 and the phosphorylation of the membrane targeting S157 residue of VASP through MAP4K4. The anti- 18 proliferative effect of complex disruption is associated with reduced YAP/TAZ target gene expression 19 and results in repressed tumor growth in the brain tissue. This dichotomous functionality of the STRIPAK 20 complex in migration and proliferation control acts through MAP4K4 regulation in tumor cells and 21 provides relevant mechanistic insights into novel tumorigenic functions of the STRIPAK complex in 22 medulloblastoma.

  • Associated 16P11.2 Deletion in Drosophila Melanogaster
    ARTICLE DOI: 10.1038/s41467-018-04882-6 OPEN Pervasive genetic interactions modulate neurodevelopmental defects of the autism- associated 16p11.2 deletion in Drosophila melanogaster Janani Iyer1, Mayanglambam Dhruba Singh1, Matthew Jensen1,2, Payal Patel 1, Lucilla Pizzo1, Emily Huber1, Haley Koerselman3, Alexis T.

Rolls1, Arjun Krishnan6,7 & 1234567890():,; Santhosh Girirajan 1,2,8 As opposed to syndromic CNVs caused by single genes, extensive phenotypic heterogeneity in variably-expressive CNVs complicates disease gene discovery and functional evaluation. Here, we propose a complex interaction model for pathogenicity of the autism-associated 16p11.2 deletion, where CNV genes interact with each other in conserved pathways to modulate expression of the phenotype. Using multiple quantitative methods in Drosophila RNAi lines, we identify a range of neurodevelopmental phenotypes for knockdown of indi- vidual 16p11.2 homologs in different tissues. We test 565 pairwise knockdowns in the developing eye, and identify 24 interactions between pairs of 16p11.2 homologs and 46 interactions between 16p11.2 homologs and neurodevelopmental genes that suppress or enhance cell proliferation phenotypes compared to one-hit knockdowns. These interac- tions within cell proliferation pathways are also enriched in a human brain-specific network, providing translational relevance in humans. Our study indicates a role for pervasive genetic interactions within CNVs towards cellular and developmental phenotypes. 1 Department of Biochemistry and Molecular Biology, The Pennsylvania State University, University Park, PA 16802, USA. 2 Bioinformatics and Genomics Program, The Huck Institutes of the Life Sciences, The Pennsylvania State University, University Park, PA 16802, USA.

  • Striatin-3G Inhibits Estrogen Receptor Activity by Recruiting a Protein Phosphatase
    199 Striatin-3g inhibits estrogen receptor activity by recruiting a protein phosphatase Bailin Tan, Xinghua Long1, Harikrishna Nakshatri2, Kenneth P Nephew1 and Robert M Bigsby Department of Obstetrics and Gynecology University School of Medicine, 975 West Walnut Street (IB360), Indianapolis, Indiana 46202, USA 1Department of Medical Sciences Program, Indiana University School of Medicine, Bloomington, Indianapolis, Indiana 47405, USA 2Department of Surgery, Indiana University School of Medicine, Indianapolis, Indiana 46202, USA (Correspondence should be addressed to R M Bigsby; Email: [email protected]) Abstract A splicing variant of rat striatin-3 (rSTRN3g) was found to associate with estrogen receptor-a (ERa) in a ligand-dependent manner. In two-hybrid and pull-down analyses, estradiol induced an interaction between rSTRN3g and ERa. STRN3g protein was found in nuclear extracts from rat uterus and human cell lines. Overexpression of rSTRN3g induced a decrease in ERa transcriptional activity but had no effect on ERb activity. Immunoprecipitation analyses showed that rSTRN3g interacts with both the ERa and the catalytic subunit of protein phosphatase 2A (PP2A(C)). The transrepressor action of rSTRN3g was overcome by okadaic acid, an inhibitor of PP2A(C), and by cotransfection of PP2A(C) siRNA. rSTRN3g caused dephosphorylation of ERa at serine 118 and this was abrogated by okadaic acid. ERa lacking phosphorylation sites at either serine 118 or 167 was insensitive to the corepressor action of rSTRN3g. These observations suggest that an rSTRN3g-PP2A(C) complex is recruited to agonist-activated ERa, thereby leading to its dephosphorylation and inhibiting transcription.
