The kinase responsible for that phosphorylation is CAK complex. M Cdk is activated by phosphorylation by CAK Alberts 17 17 Phosphorylation by from BIO 320 at University of Texas The eukaryotic cell cycle is a fundamental evolutionarily conserved process that regulates cell division from simple unicellular organisms, such as yeast, through to higher multicellular organisms, such as humans. The cell cycle comprises several phases, including the S-phase (DNA synthesis phase) and M-phase (mitotic phase). During S-phase, the genetic material is replicated, and is then docking motif mediates G2-CDK target phosphorylation in S. cerevisiae, including priming a docking site for Polo kinase Cdc5 centrosome recruitment. The study also shows how variations within cyclin motifs (RxL, PxxPxF, and ExLxF) result in different docking specificities for yeast and mammalian CDKs.

EMBO J 13: 5155–5164. PubMed Google Scholar 2019-11-13 · Here we identify a CDK phosphorylation site in the shelterin subunit at Ser365 of TRF2, whose dephosphorylation in S phase by the PP6R3 phosphatase provides a narrow window during which the RTEL1 2020-06-09 · In this way, phosphorylation and de-phosphorylation are regulatory switches that control cell cycle progression. Each stage of the cell cycle employs specific cyclin-CDK complexes. In mammalian cells, G1 cyclin-CDK4/6 is implicated in G1 phase progression, G1/S cyclin-CDK2 in the G1/S transition, S phase cyclin-CDK2 in the S phase, and M phase cyclin-CDK1 in both entry into and exit from the M phase [ 13 , 16 ]. In the beginning of the cell cycle Cdh1 is phosphorylated by M-Cdk, preventing it from attaching to APC/C.

Additional phosphorylation probably occurs on Thr14 (T14). Replacement of T160 with alanine abolishes the kinase activity of CDK2, indicating that phosphorylation at this site (as in CDC2) is required for kinase activity. Mutation of Y15 and T14 stimulates kinase activity, demonstrating that phosphorylation at these sites (as in CDC2) is inhibitory.
