coactivator

co·ac·ti·va·tor

(kō-ak'ti-vā-tŏr),
A type of nuclear proteins that participate in the potentiation of transcription of genes that are responsive to ligand-dependent transcription factors. They belong to several families, including the p160 coactivators and the CBP/p300 molecules.
[co- + activator]
