Abstract: CARF was first cloned as a novel binding partner of ARF from a yeast‐interactive screen. CARF and ARF colocalize in the perinucleolar region and have a collaborative function. In the nucleoplasm, CARF interacts with p53 and enhances its function. We demonstrate that p53 downregulates CARF in a negative feedback regulatory loop and may also involve p53 antagonist HDM2.
