NCOA3/AIB1 Overexpression Lysate

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

NCOA3/SRC3 (nuclear receptor coactivator 3/steroid receptor coactivator 3 (SRC3)) is a 155 kD member of the p160/steroid receptor coactivator family containing a nuclear localization sequence, bHLH, and PAS domain. There are two reported isoforms of this protein. NCOA3/SRC3 is localized mainly in the cytoplasm, with weak nuclear expression. The protein is translocated to the nucleus upon phosphorylation. NCOA3/SRC3 is widely expressed with high expression in the heart, skeletal muscle, pancreas, and placenta and low expression in the brain. NCOA3/SRC3 is expressed at very low levels in the lung, liver, and kidney and overexpressed in breast and ovarian cancers. This protein has histone acetyltransferase activity and functions as a transcriptional coactivator for steroid and nuclear hormone receptors. Phosphorylation by I kappaB kinase enhances coactivator function. Acetylation by CREB-BP disrupts interaction with nuclear receptors. NCOA3/SRC3 forms a multisubunit coactivation complex with NCOA2 IKKA, IKKB, IKBKG and histone acetyltransferase protein CREB binding protein and has also been shown to interact with PCAF.
