Target

  • FunctionRequired for DNA recombination, repair and replication. The activity of RP-A is mediated by single-stranded DNA binding and protein interactions.
    Functions as component of the alternative replication protein A complex (aRPA). aRPA binds single-stranded DNA and probably plays a role in DNA repair; it does not support chromosomal DNA replication and cell cycle progression through S-phase. In vitro, aRPA cannot promote efficient priming by DNA polymerase alpha but supports DNA polymerase delta synthesis in the presence of PCNA and replication factor C (RFC), the dual incision/excision reaction of nucleotide excision repair and RAD51-dependent strand exchange.
  • Post-translational
    modifications
    Phosphorylated in a cell-cycle-dependent manner (from the S phase until mitosis). Phosphorylated by ATR upon DNA damage, which promotes its translocation to nuclear foci. Can be phosphorylated in vitro by PRKDC/DNA-PK in the presence of Ku and DNA, and by CDK1.
  • Cellular localizationNucleus. Nucleus > PML body. Also present in PML nuclear bodies. Redistributes to discrete nuclear foci upon DNA damage.

  • ab2175 - immunohistochemistryFormalin fixed paraffin embedded human tonsil stained with RPA using ABC and AEC chromogen.
  • ab2175 at 1/200 staining human skin fibroblasts by ICC/IF. The cells were treated with 2mM hydroxyurea for 16 hours, formaldehyde fixed and permeabilized with 0.5% Triton X100. They were then incubated with the primary antibody for 1.5 hours at 37°C. A Cy3 ® conjugated sheep anti-mouse antibody was used as the secondary.

  • Immunohistochemical analysis of formalin-fixed, paraffin-embedded Human tonsil tissue, staining RPA32/RPA2 with ab2175. Staining was detected using DAB.
  • Overlay histogram showing HeLa cells stained with ab2175 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab2175, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
