Family relationships


EP300-interacting inhibitor of differentiation 1 (EID-1) is a nuclear protein that blocks the differentiation of skeletal muscle. It interacts with p300 and the retinoblastoma protein (Rb), and represses the transcriptional activity of MyoD. Inhibition of MyoD is linked to EID-1's ability to inhibit p300's histone acetylase activity, an essential MyoD coactivator [PMID: 11073990]. EID-1 is rapidly degraded by the proteasome as cells exit the cell cycle [PMID: 11073989]. EID-1 is also a corepressor of orphan nuclear receptor SF-1 transactivation [PMID: 18182853].
