Anti-CtIP (Ser326) Antibody

Our Anti-CtIP (Ser326) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects human CtIP (Ser326) and is antigen affinity purified from pooled serum. It is great for use in WB.

Background

CtIP, C-terminal binding protein-interacting protein, is a DNA endonuclease activated by double stranded breaks (DSBs) . DSB repairs can be performed by either one of two mechanisms; non-homologous end joining (NHEJ) or homologous recombination (HR) . NHEJ is the predominant DSB repair pathway throughout the entire cell cycle, most importantly in the G1 phase (Rothkamm et al, 2003) ; while HR is important for repairing DSBs in S and G2 phases (Beucher et al, 2009) . CtIP controls DSB resection; an event that only occurs in HR during G2-phase. Phosphorylation of Thr-847 dictates the resection efficiency (Huertas et al, 2008) . Furthermore, it has been found that DSBs undergo resection and repair in G1-phase cells via a process requiring Plk3 phosphorylation of CtIP at Ser-327 and Thr-847 (Barton et al, 2014) . Several additional phosphorylation sites within CtIP have been identified, but their significance in the repair of DNA have yet to be determined.
