Catalytic domain of Nuclear Dbf2-Related kinase-like Protein Serine/Threonine Kinases
Serine/Threonine Kinases (STKs), Nuclear Dbf2-Related (NDR) kinase subfamily, catalytic (c) domain. STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The NDR subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase. NDR kinase contains an N-terminal regulatory (NTR) domain and an insert within the catalytic domain that contains an auto-inhibitory sequence. Like many other AGC kinases, NDR kinase requires phosphorylation at two sites, the activation loop (A-loop) and the hydrophobic motif (HM), for activity. NDR kinases regulate mitosis, cell growth, embryonic development, and neurological processes. They are also required for proper centrosome duplication. Higher eukaryotes contain two NDR isoforms, NDR1 and NDR2. This subfamily also contains fungal NDR-like kinases.
