S988-p - BRCA1 (human)
Orthologous residues
BRCA1 (human): S988‑p, BRCA1 iso6 (human): , BRCA1 (mouse): S971‑p, BRCA1 (rat): S975‑p
Characterization
 Methods used to characterize site in vivo microscopy-colocalization with upstream kinase, mutation of modification site, phospho-antibody
 Relevant cell lines - cell types - tissues:  293T (epithelial), HCC1937 (breast cell), MCF-7 (breast cell)
 Cellular systems studied:  cell lines
 Species studied:  human
 Enzymes shown to modify site in vitro
Type Enzyme
KINASE Chk2 (human)
Upstream Regulation
 Potential in vivo enzymes for site: 
Type Enzyme Evidence Notes
KINASE Chk2 (human) transfection of inactive enzyme, co-immunoprecipitation
 Treatments, proteins and their effect on site modification: 
Treatments Referenced Treatments Manipulated Protein Referenced Protein Effect Notes
ionizing radiation increase
Downstream Regulation
 Effect of modification (function):  intracellular localization
 Comments:  Colocalized BRCA1 and Chk2 separate after phosphorylation of both. Phosphorylation at S988 increases survival 8 days after irradiation.
