    basic FUNCTION
  • required for chromosomal DNA replication
  • promotes initiation of chromosomal DNA replication in multicellular organisms by mediating TOPBP1- and CDK2-dependent recruitment of CDC45 onto replication origins
  • implicated in the cell cycle and is required for DNA replication
  • MCI, GMNN, and GMNC may have arisen in vertebrates through duplication of an ancestral Geminin-like gene
  • MCIDAS and GMNC are key players in the generation of multiciliated ependymal cells of the adult neurogenic niche
  • is an essential regulator of ciliogenesis in the airway epithelium and a candidate gene for mucociliary disorders
  • MCIDAS and GMNC/Lynkeas are key players on radial glial specification to ependymal cells
  • GMNC and MCIDAS specify the multiciliate cell fate by forming complexes with the E2F4/5 transcription factors to switch on a gene expression program leading to centriole amplification and cilia formation
  • required for multiciliated cells (MCCs) formation
  • mlticiliated cells (MCC) differentiation program is initiated by GMNC and MCIDAS, that activate key transcription factors, including p73 and FOXJ1, to control the multiciliogenesis program

  • interact with TOPBP1 and is a rate-limiting cyclin-dependent kinase target
  • GMNC directly transactivates the MCIDAS and FOXJ1 upstream regulatory sequences, and its activity is enhanced by E2F5 and inhibited by Geminin
