CC   -!- FUNCTION: Binds to the catalytic subunit of the cyclin dependent
CC       kinases and is essential for their biological function. {ECO:0000250}.
CC   -!- SUBUNIT: Monomer in solution; may form a homohexamer that can probably
CC       bind six kinase subunits. {ECO:0000269|PubMed:7729536}.
CC   -!- SIMILARITY: Belongs to the CKS family. {ECO:0000305}.
