Threonine 135-138 cyclin dependent kinase 1 Homo sapiens 127-131 8475101-9 1993 Furthermore, our data suggest that the phosphorylation and dephosphorylation of CDKs on Thr-14 and Tyr-15 may regulate not only the G2/M transition but also other transitions in the cell cycle and that individual cdc25 family members may regulate distinct cell cycle checkpoints. Threonine 88-91 cyclin dependent kinase 1 Homo sapiens 80-84
