- a Ser/Thr kinase
- Cdc28 is active when T169 is phosphorylated and T18 and Y19 are NOT phosphorylated (SwissProt).
The above statement was made by similarity arguments, though I have not found this statement anywhere in the literature.
- Ash1 is a potential substrate (restrict switching of mating types to mother cells)
- CKS1/YBR135W is a subunit of CDC28
