MSL1/2 ubiquitylates histone H2B on K 34. Importantly, only mono-ubiquitylation of H2B by MSL1/2 was detected in cells (data not shown), suggesting that MSL1/2, like RNF20/RNF40, was mainly a mono-ubiquitylase under physiological conditions.the MOF-MSL complex functions to promote both H4 K16ac and H2B K34ub. H2B K34ub, in turn, promotes H2B K120ub, H3 K4me3 and K79me2 to facilitate transcription elongation. |

Synthesis of mature histone mRNA requires only a single processing reaction: an endonucleolytic cleavage between a conserved stem-loop and a purine-rich downstream element to form the 3' end. The stem-loop binding protein (SLBP) is required for processing, and following processing, histone mRNA is transported to the cytoplasm, where SLBP participates in translation of the histone mRNA|We used radiolabeled probes generated by PCR targeting the open reading frame (ORF) to detect histones H2A, H2B, H3, H4, and H1 and used 7SK snRNA as a loading control (Fig. 2A). The abundance of histone H2A, H2B, H3, and H4 mRNAs is reduced to 37% to 70% of control levels in the SLBP knockdown cells when compared to the C2 control. |
