MTA2: Proteins and Enzymes

Official Gene Symbol: MTA2 Gen Bank Accession Number: NP_004730 Gene ID: 9219 (Human) Gene Map Locus: 11q12-q13.1 (human) MTA2, a homologue of human MTA1 and MTA3, is a member of highly conserved MTA gene family. It is a component of NuRD, an ATP-dependent nucleosome remodeling and histone deacetylase complex. MTA2 is a nuclear protein that interacts with HDAC1 and HDAC2 and has a functional role in chromatin remodeling and deacetylase activity. MTA2 specifically interacts with p53 and represses p53-dependant transcriptional activation, thereby regulating p53-mediated cell growth arrest and apoptosis. It also inhibits the transcriptional activity of Estrogen receptor-alpha. Northern Blot analysis detected a ubiquitous expression of MTA2.
