Specificity / Sensitivity
Microcephalin-1/BRIT1 (D38G5) Rabbit mAb detects endogenous levels of total Microcephalin-1/BRIT1 protein.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to central residues of human Microcephalin-1/BRIT1.
Microcephalin-1 (MCPH1)/BRIT1 is an early DNA damage response protein named for its mutated state in the human disease primary microcephaly. BRIT1 forms damage-induced nuclear foci, is involved in DNA damage and cell cycle checkpoints as well as regulation of mitosis. BRIT1 function is necessary for DNA damage responses, and the absence of BRIT1 function leads to genome instability. A potential tumor suppressor, BRIT1 expression is reduced in human carcinomas (1-2, reviewed in 3).
BRIT1 colocalizes with other DNA repair proteins (53BP1, MDC1, NBS1, ATM, RPA, and ATR) and is required for their activation (2). BRIT1 likely regulates DNA repair through chromatin remodeling in response to DNA damage, allowing access of repair proteins to DNA (4).
