Anti-Phospho-SRC-3/AIB-1: Polyclonal Steroid Receptor Coactivator-3, Phospho-Thr24 Antibody

BACKGROUND Nuclear hormone receptors are ligand-dependent transcription factors that require coactivators to regulate target gene expression. The steroid receptor coactivator-3 (SRC-3), also known as p/CIP, RAC3, AIB1, ACTR and TRAM-1, is a cancer-amplified coactivator in the SRC gene family which also includes SRC-1 and SRC-2. SRC-3 interacts with nuclear receptors and a subset of transcription factors, recruits histone acetyltransferases and methyltransferases for chromatin remodeling, and facilitates target gene transcription.1 SRC-3 phosphorylation and methylation have been shown to regulate coactivator complex assembly.2,3 Accumulated results from both ex vivo and animal model studies indicate that SRC-3 plays important roles in many biological processes involving cell proliferation, cell migration, cell differentiation, somatic growth, sexual maturation, female reproductive function, and vasoprotection.1 Moreover, SRC-3 has been associated with multiple cancers, including breast, gastric and prostate cancers.4 The phosphorylation of Thr24 in SRC-3 can be mediated by activation of MAP kinase pathway, which may regulate function and localization of SRC-3 proteins in cells.5
