| Abstract: | Despite minimal disparity at the sequence level, mammalian H3 variants bind to distinct sets of polypeptides. Although histone H3.1 predominates in cycling cells, our knowledge of the soluble complexes that it forms en route to deposition or following eviction from chromatin remains limited. Here, we provide a comprehensive analysis of the H3.1-binding proteome, with emphasis on its interactions with histone chaperones and components of the replication fork. Quantitative mass spectrometry revealed 170 protein interactions, whereas a large-scale biochemical fractionation of H3.1 and associated enzymatic activities uncovered over twenty stable protein complexes in dividing human cells. The sNASP and ASF1 chaperones play pivotal roles in the processing of soluble histones but do not associate with the active CDC45/MCM2-7/GINS (CMG) replicative helicase. © 2015 Elsevier Inc. |
