Summation

The interaction between the Skp2 subunit of the SCF(Skp2) complex and p27 is dependent upon Cdk2:Cyclin A/E mediated phosphorylation of p27 at Thr 187 (Carrano et al, 1999; Tsvetkov et al, 1999). There is evidence that Cyclin A/B:Cdk1 can also bind and phosphorylate p27 on Thr 187 (Nakayama et al., 2004). This phosphorylation is also essential for the subsequent ubiquitination of p27.
