Background: Histone Deacetylase 4/HDAC4

Histone Deacetylase 4 (HDAC4; also HD4) is a founding member of the class IIa subfamily, histone deacetylase family of transcriptional regulators. Although its predicted MW is 119 kDa, it runs anomalously at 140‑150 kDa in SDS‑PAGE which may be due to extensive phosphorylation plus SUMOylation. It has an N-terminal region that interacts with transcription factors and corepressors, and a C-terminal domain that shows deacetylase activity, thus repressing gene transcription. HDAC4 is found in osteoblasts, cardiac and skeletal muscle cells, and neurons. Human HDAC4 is 1084 amino acids (aa) in length. It contains one coiled-coil region (aa 67‑177), a SUMOylation site at Lys559, a histone deacetylation domain (aa 665‑993) and one NES (aa 1051‑1084). Caspase cleavage after Asp289 generates bioactive 97 and 34 kDa fragments. There is one potential splice variant that shows an alternative start site at Met118 coupled to a five aa insertion after Thr431. Over aa 1‑68, human HDAC4 shares 96% aa identity with mouse HDAC4.
