SRC1 Antibody – Rabbit Polyclonal

The protein encoded by this gene acts as a transcriptional coactivator for steroid and nuclear hormone receptors. It is a member of the p160/steroid receptor coactivator (SRC) family and like other family members has histone acetyltransferase activity and contains a nuclear localization signal, as well as bHLH and PAS domains. The product of this gene binds nuclear receptors directly and stimulates the transcriptional activities in a hormone-dependent fashion. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

SRC-1: a transcriptional coactivator for steroid and nuclear hormone receptors. A member of the p160/steroid receptor coactivator (SRC) family and like other family members has histone acetyltransferase activity and contains a nuclear localization signal, and bHLH and PAS domains. Phosphorylated and activated via the mitogen-activated protein kinase pathway. Three alternatively spliced isoforms have been described.
