RET finger protein (RFP) belongs to the large B-box RING finger protein family and is known to become oncogenic by fusion with RET tyrosine kinase. Although RFP is reported to be a nuclear protein that is present in the nuclear matrix, its function is largely unknown. RFP interacts with Enhancer of Polycomb (EPC) and strongly represses the gene transcription. Yeast two-hybrid assays revealed that the coiled-coil domain of RFP was associated with the EPcA domain and the carboxyl-terminal region of EPC. RFP may be involved in the epigenetic gene silencing mechanism cooperating with Polycomb group protein. For research use only, not for use in diagnostic procedures.
