A map of post-translational modifications of macroH2A1 splicing variants and their interactome


ABSTRACT: The aim was to characterize PTM of macroH2A1.1 and macro H2A1.2 by LC-MS/MS to facilitate the understanding of their distinct biological functions in health and disease. Next, the interactome of macroH2A1 isoforms was investigated to elucidate whether the two variants could differentially orchestrate genome maintenance and efficiency of reprogramming, i.e., two key aspects of the induced pluripotent stem cell technology (iPSC).

<b>Background:</b> Gene expression in eukaryotic cells can be governed by histone variants, which replace replication-coupled histones, conferring unique chromatin properties. MacroH2A1 is a histone H2A variant containing a domain highly similar to H2A and a large non-histone (macro) domain. MacroH2A1, in turn, is present in two alternatively exon-spliced isoforms: macroH2A1.1 and macroH2A1.2, which regulate cell plasticity and proliferation in a remarkably distinct manner. The N-terminal and th  ...[more]
