Descripción

BRCA1 is a tumor suppressor protein that plays a central role in maintaining genomic stability through its involvement in DNA damage repair, cell cycle regulation, and transcriptional control. BRCA1 functions as part of the homologous recombination repair pathway, where it recognizes and repairs double-strand DNA breaks, ensuring genomic integrity during cell division. It forms complexes with other DNA repair proteins, including RAD51, BARD1, and BRCA2, to facilitate accurate repair processes. BRCA1 also regulates cell cycle checkpoints, particularly at the G2/M phase, to prevent the propagation of damaged DNA. It is widely expressed in proliferative tissues, including breast and ovarian tissue, where its loss or mutation is associated with increased susceptibility to breast, ovarian, and other cancers. Mutations in BRCA1 disrupt its DNA repair function, leading to chromosomal instability, accumulation of mutations, and tumorigenesis. BRCA1 also interacts with signaling pathways involved in apoptosis, transcriptional regulation, and immune response, further highlighting its multifaceted role in cellular homeostasis. Knockout studies reveal defective DNA repair, increased tumorigenesis, and impaired cell cycle control, underscoring BRCA1’s critical function in DNA repair, tumor suppression, and genomic stability.

This gene encodes a nuclear phosphoprotein that plays a role in maintaining genomic stability, and it also acts as a tumor suppressor. The encoded protein combines with other tumor suppressors, DNA damage sensors, and signal transducers to form a large multi-subunit protein complex known as the BRCA1-associated genome surveillance complex (BASC). This gene product associates with RNA polymerase II, and through the C-terminal domain, also interacts with histone deacetylase complexes. This protein thus plays a role in transcription, DNA repair of double-stranded breaks, and recombination. Mutations in this gene are responsible for approximately 40% of inherited breast cancers and more than 80% of inherited breast and ovarian cancers. Alternative splicing plays a role in modulating the subcellular localization and physiological function of this gene. Many alternatively spliced transcript variants, some of which are disease-associated mutations, have been described for this gene, but the full-length natures of only some of these variants has been described. A related pseudogene, which is also located on chromosome 17, has been identified.
