Steroid receptor coactivator 1 (SRC1) is also known as nuclear receptor coactivator 1 (NCOA1). The gene encoding it is localized on human chromosome 2p23.3.[1]
Actions biochimiques/physiologiques
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 has been previously used in assays detecting ligand-dependent receptor-cofactor interactions. This protein does not contain a His tag and will be useful for assays where a native untagged protein is desired. Lane 1 corresponds to 6His-tagged and biotinylated SRC-RID; Lane 2 corresponds to biotinylated SRC-RID without 6His tag.

The p160 steroid receptor coactivator (SRC) gene family contains three homologous members, which serve as transcriptional coactivators for nuclear receptors and certain other transcription factors. These coactivators interact with ligand-bound nuclear receptors to recruit histone acetyltransferases and methyltransferases to specific

A yeast two-hybrid system was used to identify a protein that interacts with and enhances the human progesterone receptor (hPR) transcriptional activity without altering the basal activity of the promoter. Because the protein stimulated transactivation of all the steroid receptors
The binding of lipophilic hormones, retinoids and vitamins to members of the nuclear-receptor superfamily modifies the DNA-binding and transcriptional properties of these receptors, resulting in the activation or repression of target genes. Ligand binding induces conformational changes in nuclear receptors
