Polycomb group protein-mediated repression of transcription

Lluís Morey et al. Trends Biochem Sci. 2010 Jun.

Abstract

The polycomb group (PcG) proteins are essential for the normal development of multicellular organisms. They form multi-protein complexes that work as transcriptional repressors of several thousand genes controlling differentiation pathways during development. How the PcG proteins work as transcriptional repressors is incompletely understood, but involves post-translational modifications of histones by two major PcG protein complexes: polycomb repressive complex 1 and polycomb repressive complex 2.
