PA1-840 detects steroid receptor coactivator-1 (SRC-1) from human, mouse, and japaneese quail tissues and cells. PA1-840 has been successfully used in Western blot, immunocytochemistry and immunohistochemistry procedures. By Western blot, this antibody detects an ~165 kDa protein representing SRC-1 and a smaller, unknown protein at ~40 kDa from HeLa cell lysate. Immunocytochemical staining of SRC-1 in HeLa cells with PA1-840 results in nuclear staining. The PA1-840 immunogen is a synthetic peptide corresponding to residues S(8) S D P A N P D S H K R K G S P C(24) of human SRC-1. This immunizing peptide (Cat. No. PEP-044) is available for use in neutralization and control experiments.

Steroid and thyroid hormones and retinoic acid regulate a complex array of gene expression activity via intracellular receptor transcription factors belonging to the ligand dependent nuclear receptor superfamily. Adding to the complexity of function of these transcription factors are associated proteins known as coactivators and corepressors which, as their names suggest, enhance or depress transcriptional activity of the nuclear receptor with which they associate. One such coactivator is Steroid Receptor Coactivator-1 (SRC-1). SRC-1 has been shown to interact with and stimulate the transcriptional activity of estrogen, progesterone, retinoic acid, thyroid and glucocorticoid receptors, as well as retinoic X receptor (RXR) in a ligand dependent manner. The amino terminal region of SRC-1 contains a PAS-A-basic helix-loop-helix homology domain which has previously been shown to be dimerization domains in other nuclear transcription factors including the aryl hydrocarbon (Ah) receptor and its heterodimerization partner, ARNT. The carboxy-terminal region of SRC-1 has been shown to possess histone acetyltransferase activity specific primarily for histones H3 & H4.
