• PubMed Abstract: 
  

Asf1 is a ubiquitous eukaryotic histone binding and deposition protein that mediates nucleosome formation in vitro and is required for genome stability in vivo. Studies in a variety of organisms have defined Asf1's role as a histone chaperone during DNA replication through specific interactions with histones H3/H4 and the histone deposition factor CAF-I. In addition to its role in replication, conserved interactions with proteins involved in chromatin silencing, transcription, chromatin remodeling, and DNA repair have also established Asf1 as an important component of a number of chromatin assembly and modulation complexes.
