PCAF (p300/CBP associated factor) harbors acetyltransferase and a recently identified ubiquitylation activity that regulates gene expression in response to genotoxic stress or mitogenic signals. We highlight the dual role of PCAF in the control of Hedgehog signaling, a master regulator of tissue development, stemness, and tumorigenesis. By promoting histone acetylation at Hedgehog/GLI1 target gene promoters or direct ubiquitylation and proteolysis of GLI1, the PCAF/GLI1 axis stands as a promising therapeutic target for Hedgehog-dependent tumors. © 2014 Elsevier Ltd.
