    at STAGE
  • an N terminal protein kinase domain, most similar to the catalytic domain of NIMA
  • a long basic C terminus (ATP binding and activity site)
  • contains functional nuclear localization signals, and is exported from the nucleus via a nuclear export signal-dependent pathway
    interspecies homolog to rattus Nek1 (82.4 pc)
    homolog to murine Nek1 (82.9 pc)
  • protein kinase superfamily
  • Ser/Thr family of protein kinases
  • NIMA subfamily
  • CATEGORY enzyme
    SUBCELLULAR LOCALIZATION     intracellular
  • associated with the centrosomes and translocates from the nucleus during mitosis to the basal body, initiating cilia formation
  • accumulates on the chromatin during normal DNA replication
  • localize near centrosomes and play a role in centrosomal stability and ciliogenesis
  • basic FUNCTION
  • phosphorylation of serines and threonine and having a tyrosine kinase activity
  • implicated in the control of meiosis
  • may function as a kinase early in the DNA damage response pathway
  • involved in cilium control
  • CLASP2 and NEK1 proteins are present in a centrosomal complex and participate in cell cycle and cell division mechanisms
  • is involved in the beginning of the cellular response to genotoxic stress and plays an important role in preventing cell death induced by DNA damage
  • serine/threonine kinase with proposed function in DNA double-strand repair, neuronal development, and coordination of cell-cycle-associated ciliogenesis
  • involved early in a DNA damage sensing/repair pathway
  • functions independently of canonical DNA damage responses requiring the PI3 kinase-like proteins ATM and ATR
  • important for proper checkpoint control
  • 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
  • ATR-associated kinase, NEK1, enhances the stability and activity of ATR–ATRIP before DNA damage, priming ATR–ATRIP for a robust DNA damage response
  • required for the phosphorylation of multiple signaling proteins along the ATR pathway, suggesting a role of NEK1 in the initiation of ATR response
  • function of NEK1 in DNA damage signaling is critical in specific tissues
  • regulate DNA damage response, centrosome duplication and primary cilium formation

    small molecule cofactor, nucleotide,
  • ATP
  • Mg2+
  • protein
  • binding to SPERT
  • direct interaction between NEK1 and VDAC1 providing a mechanism to explain how NEK1 prevents excessive cell death, as well as the first direct evidence that a specific kinase regulates VDAC1 activity
  • NEK1 phosphorylates WWTR1 at a site essential for the ubiquitination and proteasomal degradation of PKD2
  • interaction between FKBP6 and the NIMA-related kinase-1, NEK1, and NEK1 is a possible kinase involved in cohesin redistribution in spermatocytes
  • possible regulation of VHL by NEK1 that may contribute to ciliary homeostasis and cystogenesis
  • NEK1, is critical for initiating the ATR response, and ability of NEK1 to promote ATR activation relies on the kinase activity of NEK1 and its interaction with ATR–ATRIP
  • is required for efficient CHEK1 activation in human cells
  • NEK1 may facilitate S-phase progression by interacting with XRCC5 and regulating chromatin loading of replication factors
  • CFAP410 interact with NEK1
  • role for NEK1 in the regulation of WAPL loading during meiotic prophase I, via an interaction between NEK1 and PDS5B
  • NEK1 phosphorylates PPP1CC, leading to the dephosphorylation of WAPL, which, in turn, results in its retention on chromosome cores to promote loss of cohesion at the end of prophase I in mammals
  • NEK1 competes for binding to CEP104 with the distal centriole-capping protein CCP110
