    intracellular,nucleus,nucleolus
    basic FUNCTION
  • having a protein serine/threonine kinase activity
  • critical kinase triggering CDC25A degradation by directly phosphorylating it and thus leading to its polyubiquitylation and degradation (Sorensen 2010)
  • has a role in S phase checkpoint downstream of ATR/ATM signaling (Noguchi 2002)
  • phosphorylating histone H1, H2A, H3, H2B and H4
  • NEK2, NEK6, NEK7 and NEK9 contribute to the establishment of the microtubule-based mitotic spindle, whereas NEK1, NEK10 and NEK11 have been implicated in the DNA damage response
  • CELLULAR PROCESS cell cycle, checkpoint
    nucleotide, replication

    Marker
    Therapy target inhibition of NEK11 forces checkpoint-arrested cells into mitosis and cell death, and thus is a potential target for the development of novel anticancer drugs (Sorensen 2010)
