Summary: Enables DNA-binding transcription activator activity; damaged DNA binding activity; and transcription cis-regulatory region binding activity. Involved in double-strand break repair and positive regulation of transcription by RNA polymerase II. Acts upstream of with a positive effect on negative regulation of gene expression via chromosomal CpG island methylation. Acts upstream of or within several processes, including centrosome cycle; mitotic G2/M transition checkpoint; and random inactivation of X chromosome. Located in chromosome; cytoplasm; and male germ cell nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system; and integumental system. Used to study breast cancer; hereditary breast ovarian cancer syndrome; and ovarian cancer. Human ortholog(s) of this gene implicated in several diseases, including Fanconi anemia complementation group S; breast cancer (multiple); cervix uteri carcinoma in situ; gastrointestinal system cancer (multiple); and reproductive organ cancer (multiple). Orthologous to human BRCA1 (BRCA1 DNA repair associated). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
