- Abstract
Jun dimerization protein-2 (JDP2) is a component of the AP-1 transcription factor that represses transactivation mediated by the Jun family of proteins. Here, we examine the functional mechanisms of JDP2 and show that it can inhibit p300-mediated acetylation of core histones in vitro and in vivo. Inhibition of histone acetylation requires the N-terminal 35 residues and the DNA-binding region of JDP2. In addition, we demonstrate that JDP2 has histone-chaperone activity in vitro. These results suggest that the sequence-specific DNA-binding protein JDP2 may control transcription via direct regulation of the modification of histones and the assembly of chromatin.
