a DNA-dependent ATPase and DNA helicase required for the maintenance of chromosomal stability. Involved in the repair of DNA double-strand breaks by homologous recombination in a manner that depends on its association with BRCA1. Binds directly to the BRCT domains of BRCA1. Defects in BRIP1 cause of susceptibility to breast cancer and Fanconi anemia. Acts late in the Fanconi anemia pathway, after FANCD2 ubiquitination. Belongs to the DEAD box helicase family, DEAH subfamily. Two alternatively spliced human isoforms have been described. Note: This description may include information from UniProtKB.
