Transcriptional adapter 2-alpha

UniProtKB accession:  Q8CHV6

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Component of the ATAC complex, a complex with histone acetyltransferase activity on histones H3 and H4 (By similarity). Required for the function of some acidic activation domains, which activate transcription from a distant site (By similarity). Binds double-stranded DNA (PubMed:16299514). Binds dinucleosomes, probably at the linker region between neighboring nucleosomes (PubMed:16299514). Plays a role in chromatin remodeling (By similarity). May promote TP53/p53 'Lys-321' acetylation, leading to reduced TP53 stability and transcriptional activity (By similarity). May also promote XRCC6 acetylation thus facilitating cell apoptosis in response to DNA damage (By similarity).
