Steroid receptor coactivator 1 (SRC1) is a transcriptional coactivator that mediates the activating functions of many of the nuclear hormone receptors. It is also known as NCoA1 and is a member of the SRC/p160 coactivator family. SRC1 has been shown to be over expressed in some cancers. SRC1 is a 160 kDa protein that contains several LXXLL motifs, which are involved in nuclear receptor interaction. The region 627-786 contains 3 LXXLL motifs that are involved in interaction with nuclear hormone receptorsand have been previously used in assays detecting ligand-dependent receptor-cofactor interactions. This protein contains the Tobacco Etch virus (TEV) protease site and can be cleaved using acTEV to yield untagged SRC1 RID. This protein will be useful for assays where a native untagged protein is desired.
