comment
  • FUNCTION Guanine-nucleotide releasing factor that promotes the exchange of Ran-bound GDP by GTP, and thereby plays an important role in RAN-mediated functions in nuclear import and mitosis (PubMed:11336674, PubMed:17435751, PubMed:1944575, PubMed:20668449, PubMed:22215983, PubMed:29042532). Contributes to the generation of high levels of chromosome-associated, GTP-bound RAN, which is important for mitotic spindle assembly and normal progress through mitosis (PubMed:12194828, PubMed:17435751, PubMed:22215983). Via its role in maintaining high levels of GTP-bound RAN in the nucleus, contributes to the release of cargo proteins from importins after nuclear import (PubMed:22215983). Involved in the regulation of onset of chromosome condensation in the S phase (PubMed:3678831). Binds both to the nucleosomes and double-stranded DNA (PubMed:17435751, PubMed:18762580).SUBUNIT Interacts with RAN (PubMed:11336674, PubMed:17435751, PubMed:18762580, PubMed:29040603). Interacts with KPNA3 (PubMed:34564892). Interacts (via N-terminus and RCC1 repeats) with KPNA4 (PubMed:29042532). Interacts with ARRB2; the interaction is detected in the nucleus upon OR1D2 stimulation (PubMed:16820410).INTERACTION Predominantly nuclear in interphase cells (PubMed:12194828). Binds to mitotic chromosomes (PubMed:12194828, PubMed:17435751, PubMed:20668449).ALTERNATIVE PRODUCTS N-terminal methylation by METTL11A/NTM1 is required for binding double-stranded DNA and stable chromatin association. Di- and trimethylation produce a permanent positive charge on the amino group, which facilitates electrostatic binding to the phosphate groups on DNA, while inhibiting histone-binding. Methylated tail helps retain RCC1 on chromosomes during nucleotide exchange on Ran.DISEASE The disease is caused by variants affecting the gene represented in this entry.MISCELLANEOUS Patients with Raynaud disease produce antibodies that bind to RCC1.
