  • also located on the ribosome, the nucleus membrane
  • basic FUNCTION
  • identifying origins prior to assembly of pre-initiation complexes
  • polydactyl zinc-finger protein with weak replication enhancing activity and so far unknown cellular function
  • sequence-specific double-strand DNA-binding protein required for initiation of chromosomal DNA replication
  • facilitating DNA bending
  • may act as accessory factors in origin identification prior to the assembly of pre-initiation complexes
  • acts as a sequence-specific DNA binding protein which has a main function as accessory factor in origin identification during DNA replication
  • with geminin act as a previously undescribed repressor complex distinct from REST to negatively regulate the expression of target genes in nonneuronal cells suggesting that the REPIN1-geminin complex may contribute to suppressing the precocious expression of target genes in fetal brain
  • potential role in the regulation of adipocyte size and expression of glucose transporters SLC2A1 and SLC2A4 in adipocytes
  • has weak replication enhancing activity and may act as an accessory factor in origin identification prior to the assembly of pre-initiation complexes
  • regulates the expression of genes involved in adipogenesis, lipid droplet formation and fusion, glucose and fatty acid transport in 3T3-L1 adipocytes
  • potential role as regulator of adipocyte size and seems to be involved in the regulation of genes involved in adipogenesis, lipid droplet formation and fusion, glucose and fatty acid transport in adipocytes
  • CELLULAR PROCESS nucleotide, replication
