RNA recognition motif 1 and 2 in poly [ADP-ribose] polymerase 10 (PARP-10) and similar proteins
This subgroup corresponds to the RRM1 and RRM2 of PARP-10, a novel oncoprotein c-Myc-interacting protein with poly(ADP-ribose) polymerase activity. It is localized to the nuclear and cytoplasmic compartments. In addition to the PARP activity, PARP-10 is also involved in the control of cell proliferation by inhibiting c-Myc- and E1A-mediated cotransformation of primary cells. PARP-10 may play a role in nuclear processes including the regulation of chromatin, gene transcription, and nuclear/cytoplasmic transport. It contains two N-terminal RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains), two overlapping C-terminal domains composed of a glycine-rich region and a region with homology to catalytic domains of PARP enzymes (PARP domain). In addition, PARP-10 contains two ubiquitin-interacting motifs (UIM).
