CC   -!- FUNCTION: Binds to the catalytic subunit of the cyclin dependent
CC       kinases and is essential for their biological function. {ECO:0000250}.
CC   -!- SUBUNIT: Forms a homohexamer that can probably bind six kinase
CC       subunits. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the CKS family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=EDR41107.2; Type=Miscellaneous discrepancy; Note=Unusual initiator. The initiator methionine is coded by a non-canonical TTG leucine codon.; Evidence={ECO:0000305};
