CC   -!- FUNCTION: Histone deacetylase that catalyzes the deacetylation of
CC       lysine residues on the N-terminal part of the core histones (H2A, H2B,
CC       H3 and H4), and some other non-histone substrates. Histone
CC       deacetylation gives a tag for epigenetic repression and plays an
CC       important role in transcriptional regulation, cell cycle progression
CC       and developmental events. Histone deacetylases act via the formation of
CC       large multiprotein complexes. Participates in the BCL6 transcriptional
CC       repressor activity by deacetylating the H3 'Lys-27' (H3K27) on enhancer
CC       elements, antagonizing EP300 acetyltransferase activity and repressing
CC       proximal gene expression. Also functions as a deacetylase for non-
CC       histone targets. In addition to protein deacetylase activity, also acts
CC       as a protein-lysine deacylase by recognizing other acyl groups:
CC       catalyzes removal of (2E)-butenoyl (crotonyl) and 2-hydroxyisobutanoyl
CC       (2-hydroxyisobutyryl) acyl groups from lysine residues, leading to
CC       protein decrotonylation and de-2-hydroxyisobutyrylation, respectively.
