Murine p202 is an interferon-inducible primarily nuclear phosphoprotein (52 kDa) whose expression in transfected cells inhibits colony formation. p202-binding proteins include the pocket proteins (pRb, p107 and p130), a p53-binding protein (sm53BP1), and transcription factors (e.g. NF-kappaB (p50 and p65), AP-1 (c-Fos and c-Jun), E2F-1, E2F-4, MyoD, and myogenin). p202 modulates the transcriptional activity of these factors in transfected cells. Here we demonstrate that p202 self-associates directly and a sequence in p202, which is conserved among the members of the 200-family proteins, was sufficient for self-association in vitro. Our observations reported herein raise the possibility that self-association of p202 may provide a mechanism for the regulation of its activity.
