MGI Phenotype FUNCTION: This gene encodes a member of the DEAH subfamily of DEAD box helicases. A similar protein in humans is both a DNA-dependent ATPase and a 5-prime-to-3-prime DNA helicase, and plays a role in the repair of DNA double stranded breaks through interaction with the breast cancer-associated tumor suppressor BRCA1. [provided by RefSeq, Feb 2011]
PHENOTYPE: Mice homozygous for a gene trapped allele exhibit gonadal atrophy, subfertility, germ cell attrition, epithelial tumor predisposition, increased cellular sensitivity to interstrand crosslink-inducing agents, hypersensitivity to replication inhibitors, and predisposition to lymphoma.

Protein Function and Prediction

BRIP1 directly binds to BRCA1 (1); it functions as a DNA-dependent ATPase and a 5’-to-3’ DNA helicase (2).  The association of BRIP1 with BRCA1 is cell cycle regulated and is required for DNA damage-induced checkpoint control during the transition from G2 to M phase (3).  Further studies propose that, through the association with BRCA1, Brip1 facilitates BRCA1 DNA repair and possibly the localization of BRCA1 to DNA damage foci (4).  BRIP1 is necessary to promote homologous recombination after DNA double-stranded breaks (5).

Expression/Localization

Northern blot analysis determined that BRIP1 is ubiquitously expressed with highest levels in the testis (1).

Background

Mutations in BRIP1 are linked to early-onset breast cancer [OMIM: #114480; (1;6)] and Fanconi anemia, complementation group J [FA-J; OMIM: #609054; (7)].  FA-J is  a clinically and genetically heterogeneous disorder that causes genomic instability. FA-J causes developmental abnormalities in major organ systems, early-onset bone marrow failure, and a high predisposition to cancer.
