Chromatin structure is known to tune the function of bound TFs by nucleosome positioning, histone modification, and the
incorporation of histone variants [1]. However the specific contribution of each component of chromatin has been
We recently reported that we identified hitherto unknown fourteen histone H3 variants and that they were detected in a
variety of tissues [2]. Our functional analysis revealed that H3mm7, one of the newly discovered histone H3 variants, was
required for skeletal muscle differentiation. H3mm7 knockout in C2C12 myoblasts resulted in rigid chromatin structure
and in the reduction of transcription levels of a subset of the genes into which H3mm7 was incorporated. The data
suggest that H3mm7 and other variants contribute to set the baselines of transcription levels. I will discuss other recent
advances in understanding the novel histone H3 variants.
