Conserved domains of RPD3/HDA1 family histone deacetylases in Arabidopsis. Conserved domains of RPD3/HDA1 histone deacetylases in Arabidopsis thaliana are shown with their corresponding amino acid length on the right. Arrows indicate histidine active site in histone deacetylase (HD) domain. Abbreviations and amino acid residues in parenthesis: PB, Pfam B database; DUF, domain of unknown function; G, poly-glycine rich region (HDA6: 311–314, HDA7: 302–305, HDA9: 296–299, HDA17: 27–31); Asp, aspartate rich region (HDA6: 428–465, HDA9: 384–424, HDA10: 100–140, HDA17: 116–156, HDA15: 58–77); BAD, BH3-only pro-apoptotic domain; ad, aldehyde dehydrogenase (HDA15: 25–36); ZF, Zinc finger (86–115); 60s RP, ribosomal protein (193–203); CR6, cytokine-responsive protein 6 interacting protein (402–559); LZ, leucine zip motif (457–478); CC, coiled-coil domain (430–610); COG6, conserved oligomeric golgi complex 6 (629–641); RtcR, RNA terminal phosphate cyclase regulator (297–312); NLS, nuclear localization signal (HDA6:17–20 and 14–20, HDA19: 12–18 and 428–434, HDA5: 10–26, HDA14: 406–412, HDA15: 14–17, 521–537 and 522–538, HDA18: 43–59 and 121–137); NES, nuclear export signal (HDA2, 180–187 and 245–257, HDA8: 162–168, HDA15: 484–491, HDA18: 538–549).
