Located In

This protein is located in 5 target(s):

Target	Category	Definition
nucleus	cellular component	A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. [GOC:go_curators]
nucleoplasm	cellular component	That part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653]
cytoplasm	cellular component	The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. [ISBN:0198547684]
nuclear speck	cellular component	A discrete extra-nucleolar subnuclear domain, 20-50 in number, in which splicing factors are seen to be localized by immunofluorescence microscopy. [http://www.cellnucleus.com/]
cytoplasmic ribonucleoprotein granule	cellular component	A ribonucleoprotein granule located in the cytoplasm. [GOC:bf, GOC:PARL, PMID:15121898]

Target	Category	Definition
nuclear ubiquitin ligase complex	cellular component	A ubiquitin ligase complex found in the nucleus. [GOC:mah]
BRCA1-BARD1 complex	cellular component	A heterodimeric complex comprising BRCA1 and BARD1, which possesses ubiquitin ligase activity and is involved in genome maintenance, possibly by functioning in surveillance for DNA damage. [PMID:12787778]
BRCA1-A complex	cellular component	A protein complex that contains the BRCA1-BARD1 heterodimer, RAP80/UIMC1, BRCC3/BRCC36, BRE/BRCC45, FAM175A/CCDC98/Abraxas and MERIT40/NBA1, and specifically recognizes and binds K63-linked polyubiquitin chains present on histone H2A and H2AX at DNA damage sites. [GOC:mah, PMID:19261749]
BRCA1-B complex	cellular component	A protein complex that contains the BRCA1-BARD1 heterodimer, BACH1 and TopBP1, and binds to DNA during S phase at DNA damage sites. [GOC:mah, PMID:16391231]

BRCA1-C binding ta damaged DNA is required for DNA damage-induced Chk1 phosphorylation and the G2/M transition checkpoint. [GOC:mah, PMID:15485915, PMID:16391231]
ubiquitin ligase complex	cellular component	A protein complex that includes a ubiquitin-protein ligase and enables ubiquitin protein ligase activity. The complex also contains other proteins that may confer substrate specificity on the complex. [GOC:jh2, PMID:9529603]

tissue homeostasis	biological process	A homeostatic process involved in the maintenance of an internal steady state within a defined tissue of an organism, including control of cellular proliferation and death and control of metabolic function. [GOC:add, GOC:isa_complete]
DNA repair	biological process	The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway. [PMID:11563486]
