Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0000200
UniProt IDP54253
Primary gene name(s)ATXN1
Synonym gene name(s)ATX1, SCA1
Protein nameAtaxin-1
Protein functionChromatin-binding factor that repress Notch signaling in the absence of Notch intracellular domain by acting as a CBF1 corepressor. Binds to the HEY promoter and might assist, along with NCOR2, RBPJ-mediated repression. Binds RNA in vitro. May be involved in RNA metabolism. {ECO:0000269|PubMed:21475249}.
Subcellular locationCytoplasm {ECO:0000269|PubMed:7647801}. Nucleus {ECO:0000269|PubMed:12093161, ECO:0000269|PubMed:7647801}. Note=Colocalizes with USP7 in the nucleus. {ECO:0000269|PubMed:12093161}.
