ABSTRACT
The protein kinase p34cdc2 is a key regulator of the cell cycle in all eukaryotes. Its activity is controlled by cell cycle-dependent interactions with other proteins, notably cyclins, and by changes in its phosphorylation state. Two inhibitory phosphorylation sites in chicken p34cdc2 have previously been mapped to threonine 14 and tyrosine 15. Here we describe the identification of threonine 161 as an additional in vivo phosphorylation site in vertebrate p34cdc2. Phosphorylation of this site is cell cycle dependent and likely to be required for p34cdc2 activity.
