NCBI Protein Information
histone deacetylase 6
NCBI Summary
RPD3-like histone deacetylase. HDA6 mutations specifically increase the expression of auxin-responsive transgenes, suggesting a role in transgene silencing.

UniProt Comments
Responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Might remove acetyl residues only from specific targets, such as rDNA repeats or complex transgenes. Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes. Required for rRNA gene silencing in nucleolar dominance. Plays a role in transgene silencing, but this effect seems to bee independent of the histone deacetylase activity (PubMed:11340181, PubMed:12486004, PubMed:15037732, PubMed:16648464). Part of the AS1 repressor complex to regulate the KNOX expression in leaf development (PubMed:23271976). Binds to KNAT1, KNAT2, and KNATM chromatin (PubMed:23271976).
