背景(Background)
This gene encodes a protein with sequence similarity to retinoblastoma-binding protein-1. The encoded protein is a subunit of the histone deacetylase-dependant SIN3A transcriptional corepressor complex, which functions in diverse cellular processes including proliferation, differentiation, apoptosis, oncogenesis, and cell fate determination. The gene product is recognized by IgG antibody isolated from a breast cancer patient and appears to be a molecular marker associated with a broad range of human malignancies. Alternate transcriptional splice variants encoding different isoforms have been characterized. [provided by RefSeq, Jul 2008],
功能
domain:The ARID domain is involved in stabilizing the mSin3A corepressor complex on DNA.,domain:The C-terminus mediates interaction with mSin3A corepressor complex.,domain:The N-terminus is involved in transcriptional repression by HDAC-independent mechanisms.,function:Acts as a transcriptional repressor. May function in the assembly and/or enzymatic activity of the Sin3A corepressor complex or in mediating interactions between the complex and other regulatory complexes.,similarity:Contains 1 ARID domain.,subcellular location:Cytoplasmic in breast cancer cells.,subunit:Component of a Sin3A corepressor complex consisting of SIN3A, SAP130, SUDS3/SAP45, SAP180, HDAC1 and HDAC2.,tissue specificity:Highly expressed in the testis and in breast, lung, colon, pancreatic and ovarian cancers. Expressed at low levels in the thymus, prostate and ovary.,
