HDAC1 has intrinsic protease activity and regulates transcription through clipping histone H3 N-terminal tail
In this study, we have uncovered novel proteolytic processing of the histone H3 tail in senescence models in primary fibroblasts and melanocytes. Cleavage of H3 tail occurs at two distinct residues and is mediated by Cathepsin L. We show that variant H3.3 is preferentially cleaved, and that cleaved ...
ORGANISM(S): Homo sapiens 
Histone deacetylase 1 (HDAC1) has been mainly characterized as a factor removing acetyl groups from histone and non-histone proteins as well as inhibiting gene transcription. However, HDAC1 is also involved in positively regulating transcription of particular genes through as yet unknown mechanisms....

MMP-9 drives melanomagenic transcription program through histone H3 tail proteolysis
The proteolytic cleavage of histone tails, also termed histone clipping, has been described as a mechanism for permanent removal of post-translational modifications (PTMs) from histone proteins. Such activity has been ascribed to ensure regulatory function in key cellular processes such as different...
