Histone deacetylase 4, also known as HDAC4, is a protein that in humans is encoded by the HDAC4 gene.^[5][6]

Function[edit]

Histones play a critical role in transcriptional regulation, cell cycle progression, and developmental events. Histone acetylation/deacetylation alters chromosome structure and affects transcription factor access to DNA. The protein encoded by this gene belongs to class II of the histone deacetylase/acuc/apha family. It possesses histone deacetylase activity and represses transcription when tethered to a promoter. This protein does not bind DNA directly but through transcription factors MEF2C and MEF2D. It seems to interact in a multiprotein complex with RbAp48 and HDAC3.^[7] Furthermore, HDAC4 is required for TGFbeta1-induced myofibroblastic differentiation.^[8]

Clinical significance[edit]

Studies have shown that HDAC4 regulates bone and muscle development. Harvard University researchers also concluded that it promotes healthy vision: Reduced levels of the protein led to the death of the rod photoreceptors and bipolar cells in the retinas of mice.^[9][10]

Interactions[edit]

HDAC4 has been shown to interact with:
