Abstract

Chromatin assembly factor 1 (CAF-1) assembles nucleosomes in a replication-dependent manner. The small subunit of CAF-1 (p48) is a member of a highly conserved subfamily of WD-repeat proteins. There are at least two members of this subfamily in both human (p46 and p48) and yeast cells (Hat2p, a subunit of the B-type H4 acetyltransferase, and Msi1p). Human p48 can bind to histone H4 in the absence of CAF-1 p150 and p60. p48, also a known subunit of a histone deacetylase, copurifies with a chromatin assembly complex (CAC), which contains the three subunits of CAF-1 (p150, p60, p48) and H3 and H4, and promotes DNA replication-dependent chromatin assembly. CAC histone H4 exhibits a novel pattern of lysine acetylation that overlaps with, but is distinct from, that reported for newly synthesized H4 isolated from nascent chromatin. Our data suggest that CAC is a key intermediate of the de novo nucleosome assembly pathway and that the p48 subunit participates in other aspects of histone metabolism.
