High impact information on ptr3

  • Localization of a nucleoplasmin-green fluorescent protein fusion suggests that ptr2 and ptr3 have defects also in nuclear protein import [1].
  • The ptr3+ gene is essential for cell viability, and Ptr3p tagged with green fluorescent protein was localized in both the nucleus and the cytoplasm [1].
  • We cloned the ptr2+ and ptr3+ genes and found that they encode Schizosaccharomyces pombe homologues of the mammalian RCC1, a guanine nucleotide exchange factor for RAN/TC4, and the ubiquitin-activating enzyme E1 involved in ubiquitin conjugation, respectively [1].
