    Danaher Inc ab4074 anti phospho histone h2a x ser139 mouse monoclonal ab
    A) Illustration of the BRCA1 polypeptide and a simplified interaction engagements. The C-terminal BRCT domain of BRCA1 interacts in a mutually exclusive manner with the phosphorylated isoforms of ABRAXAS, BACH1, or CtIP to form distinct BRCA1 complexes. In addition, BRCA1 harbors a coiled-coil motif that mediates its interaction with PALB2 and the recruitment of BRCA2 and RAD51 to sites of DNA damage. The mutant mouse alleles used in this study: Brca1tr encodes a pathogenic truncating mutation, denoted with a red arrow, that eliminates the BRCT domains. AbraxasS404A, Bach1S994A and CtipS326A each encode a missense mutation that eliminates a phosphorylation site necessary for the interaction of its protein product with the BRCT domain of BRCA1. B) Morphology and size of E13.5 embryos. The difference between wt ctrl and AABBCC was evaluated with an unpaired two-tailed student’s t-test.; wt ctrl n = 9, AABB n = 5, BBCC n = 4, AACC n = 3, AABBCC n = 3. C) Rad51 foci immunofluorescence and quantification in induced pluripotent stem (iPS) cell lines treated with 10Gy IR. Data was analyzed by one-way ANOVA.; wt ctrl n = 3, AABB n =3, BBCC n = 3, AACC n = 4, AABBCC n = 4; A = Abraxas S404A/S404A, B = Bach1 S994A/S994A, C = CtIP S326A/S326A; scale bar = 10μm. D) CRISPR/Cas9 based HDR assay with induced pluripotent stem (iPS) cell lines, shown as a ratio of dual allele targeting in each genotype vs. control. Statistical analysis with one-way ANOVA, except for BBCC vs. AABBCC and AACC vs AABBCC, which used unpaired two-tailed student’s t-tests.; wt ctrl n = 4, AABB n = 4, BBCC n = 3, AACC n = 5, AABBCC n= 5. E) DNA fork stalling in immortalized MEFs. At least 150 DNA fibers were measured per genotype. Analysis with one-way ANOVA. F) Immunofluorescence and quantification for <t>phospho-H2AX</t> (S139). Foci were counted on reprogramming day 5 in > 138 cells/genotype. Statistical analysis with one-way ANOVA. Size bar = 5μm, applicable to all panels.

AbraxasS404A, Bach1S994A and CtipS326A each encode a missense mutation that eliminates a phosphorylation site necessary for the interaction of its protein product with the BRCT domain of BRCA1. B) Morphology and size of E13.5 embryos. The difference between wt ctrl and AABBCC was evaluated with an unpaired two-tailed student’s t-test.; wt ctrl n = 9, AABB n = 5, BBCC n = 4, AACC n = 3, AABBCC n = 3.
