p55 is a common component of many chromatin-modifying complexes and has been shown to bind to histones. Here, we present a crystal structure of Drosophila p55 bound to a histone H4 peptide. p55, a predicted WD40 repeat protein, recognizes the first helix of histone H4 via a binding pocket located on the side of a beta-propeller structure. The pocket cannot accommodate the histone fold of H4, which must be altered to allow p55 binding. Reconstitution experiments show that the binding pocket is important to the function of p55-containing complexes. These data demonstrate that WD40 repeat proteins use various surfaces to direct the modification of histones.

Function

CAF1_DROME Core histone-binding subunit that may target chromatin assembly factors, chromatin remodeling factors and histone deacetylases to their histone substrates in a manner that is regulated by nucleosomal DNA. Component of several complexes which regulate chromatin metabolism. These include the chromatin assembly factor 1 (CAF-1) complex, which is required for chromatin assembly following DNA replication and DNA repair; the nucleosome remodeling and deacetylase complex (the NuRD complex), which promotes transcriptional repression by histone deacetylation and nucleosome remodeling; the nucleosome remodeling factor (NURF) complex, which catalyzes ATP-dependent nucleosome sliding and facilitates transcription of chromatin; and the polycomb group (PcG) repressor complex ESC-E(Z), which promotes repression of homeotic genes during development. Also required for transcriptional repression of E2F target genes by E2f2 and Rbf or Rbf2.[1] [2] [3] [4] [5]
