Nuclear Receptor Coactivators
Proteins that enhance gene expression when associated with ligand bound activated NUCLEAR RECEPTORS. The coactivators may act through an enzymatic process that affects the rate of transcription or the structure of chromatin. Alternatively nuclear receptor coactivators can function as adaptor proteins that bring nuclear receptors into close proximity with transcriptional complexes.
