PHD finger found in PHD and RING finger domain-containing protein 1 (PHRF1) PHRF1, also termed KIAA1542, or CTD-binding SR-like protein rA9, is a ubiquitin ligase that induces the ubiquitination of TGIF (TG-interacting factor) at lysine 130. It acts as a tumor suppressor that promotes the transforming growth factor (TGF)-beta cytostatic program through selective release of TGIF-driven promyelocytic leukemia protein (PML) inactivation. PHRF1 contains a plant homeodomain (PHD) finger and a RING finger.
