Uniform diversity: a genome-wide study of PRC1 ortholog localization

Polycomb-group proteins are a well-characterized family of proteins involved in chromatin remodeling. In mammals, Polycomb-group proteins form two multiprotein complexes: Polycomb repressive complex 2 (PRC2), which represses gene expression, and PRC1. PRC1, unlike its highly conserved sister, is a masterpiece of variety. It comprises the subunits Polycomb (Pc), Posterior sex combs (Psc), Polyhomeotic (Ph) and… Read more »
