CC -!- FUNCTION: Serine/threonine-protein kinase that plays a central role in
CC centriole duplication. Able to trigger procentriole formation on the
CC surface of the mother centriole cylinder, using mother centriole as a
CC platform, leading to the recruitment of centriole biogenesis proteins
CC such as sas-6. When overexpressed, it is able to induce centrosome
CC amplification through the simultaneous generation of multiple
CC procentrioles adjoining each parental centriole during S phase.
CC Centrosome amplification following overexpression can initiate
CC tumorigenesis, highlighting the importance of centrosome regulation in
CC cancers (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-

CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton, microtubule organizing
CC center, centrosome, centriole {ECO:0000250}.
CC -!- PTM: Ubiquitinated by the SCF(Slimb) ubiquitin ligase complex; leading
CC to its degradation by the proteasome during interphase and regulating
CC centriole number and ensuring the block to centriole reduplication.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr protein
CC kinase family. CDC5/Polo subfamily. {ECO:0000255|PROSITE-
CC ProRule:PRU00159, ECO:0000255|PROSITE-ProRule:PRU01328,
