EP300-interacting inhibitor of differentiation 1 (EID1)

Interacts with RB1 and EP300 and acts as a repressor of MYOD1 transactivation.

Inhibits EP300 and CBP histone acetyltransferase activity.

May be involved in coupling cell cycle exit to the transcriptional activation of genes required for cellular differentiation. May act as a candidate coinhibitory variable for NR0B2 which may be directly connected to transcription inhibitory mechanisms.
