Antibodies are purified by protein A and peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\nThere are three members of the steroid receptor co-activator (SRC) family of proteins: SRC-1 (NCoA-1), SRC-2 (TIF2\/GRIP1\/NCoA-2), and SRC-3 (ACTR\/pCIP\/RAC3\/TRAM-1\/AIB1). All SRC family members share significant structural homology and function to stimulate transcription mediated by nuclear hormone receptors and other transcriptional activators such as Stat3, NF-κB, E2F1, and p53 (1-4). Two SRC proteins, SRC-1 and SRC-3, function as histone acetyltransferases (5,6). In addition, all three family members can recruit other histone acetyltransferases (CBP\/p300, PCAF) and histone methyltransferases (PRMT1, CARM1) to target promoters and cooperate to enhance expression of many genes (5-8). The SRC proteins play important roles in multiple physiological processes including cell proliferation, cell survival, somatic cell growth, mammary gland development, female reproductive function, and vasoprotection (9). SRC-1 and SRC-3 are conduits for kinase-mediated growth factor signaling to the estrogen receptor and other transcriptional activators. Seven SRC-1 phosphorylation sites and six SRC-3 phosphorylation sites have been identified, which are induced by steroids, cytokines, and growth factors and involve multiple kinase signaling pathways (9-11). Research has shown that all three SRC family members are associated with increased activity of nuclear receptors in breast, prostate, and ovarian carcinomas. According to the literature, SRC-3 is frequently amplified or overexpressed in a number of cancers (12), and SRC-1\/PAX3 and SRC-2\/MYST3 translocations are found associated with rhabdomyosarcoma and acute myeloid leukemia, respectively (13,14). Phosphorylation of Thr24 of SRC-3 proteins can be induced by stimulation with EGF. Phosphorylated SRC-3 translocates from the cytoplasm to the nucleus where it interacts with other transcription factors and steroid hormone receptors and regulates gene expression (15).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nACTR; AIB-1; AIB1; Amplified in breast cancer 1 protein; BHLHE42; CAGH16; CBP-interacting protein; Class E basic helix-loop-helix protein 42; CTG26; KAT13B; MGC141848; NCoA-3; NCOA3; Nuclear receptor coactivator 3; pCIP; RAC-3; RAC3; Receptor-associated coactivator 3; SRC-3; SRC3; Steroid receptor coactivator protein 3; Thyroid hormone receptor activator molecule 1; TNRC14; TNRC16; TRAM-1; TRAM1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 160\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46798062878889,"sku":"2979S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-2979s","provider":"Iright","version":"1.0","type":"link"}
