DESCRIPTION

Also known as SCM_DROME, Scm. Polycomb group (PcG) protein. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. They probably act via the methylation of histones, rendering chromatin heritably changed in its expressibility. Scm associates with the PRC1 core complex containing PSC, PC, PH and Sce/RING1. Forms homotypic and heterotypic interactions. Interacts with the SAM domain of ph-p via its SAM domain in vitro. Interacts with corto in vitro.
