The antigen is a  phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser239 of human ATRIP.

The antibody is prepared from pooled rabbit serum by affinity purification via sequential chromatography on phospho- and dephospho-peptide affinity columns.

Biological Significance: ExpandCollapse

ATRIP, ATR interacting protein, binds to ATR to regulate ATR expression, and is an essential component of the DNA damage checkpoint pathway (Cortez et al, 2001). ATR is recruited to DNA lesions in part through its association with ATRIP, which in turn interacts with the single-stranded DNA binding protein RPA (Ball et al, 2007). DNA replication forks may stall as a result of DNA damage causing phosphorylation of several proteins, including BRCA1 when colocalizing with ATR/ATRIP complex and RPA (Venere et al, 2007). The DNA replication fork stall coincides with BRCA1 directly phosphorylating ATRIP at Ser239 (Venere et al, 2007).


100 µl in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots.

For long term storage –20° C is recommended. Stable at –20° C for at least 1 year.

ATRIP ser239 Antibody
Western blot of mouse testicular lysate showing specific immunolabeling of the ~86 kDa ATRIP protein phosphorylated at Ser239 in the first lane (-). Phosphospecificity is shown in the second lane (+) where the immunolabeling is completely eliminated by lysate treatment with lambda phosphatase (λ-Ptase, 800 units/1mg protein for 30 minutes).
