Structure of Arabidopsis HISTONE DEACETYLASE15.

Mammalian histone deacetylases (HDACs) undergo phosphorylation to regulate their localization, activity, and function. However, little is known about the regulation of plant HDAC function and activity by phosphorylation. Here, we report the crystal structure of the Reduced Potassium Dependency3/Histone Deacetylase1 (RPD3/HDA1) type class II histone deacetylase HDA15 in Arabidopsis ().
