High impact information on PCNP

  • PCNP was readily ubiquitinated in 293 and COS-7 cells, and NIRF ubiquitinated PCNP in vitro as well as in vivo [1].
  • Considering that NIRF is implicated in cell cycle regulation, these findings suggest that NIRF and PCNP are a ubiquitin ligase and its substrate, respectively, and may constitute a novel signaling pathway with some relation to cell proliferation [1].
  • Furthermore, the NIRF gene is just within small amplicons in some tumors, suggesting that PCNP and NIRF might be involved in some aspects of tumorigenesis [2].
