The p27(Kip1) protein has now been shown to be phosphorylated in vivo, and this phosphorylation reduces the electrophoretic mobility of the protein. Substitution of Ser(10) with Ala (S10A) markedly reduced the extent of p27(Kip1) phosphorylation and prevented the shift in electrophoretic mobility. Phosphopeptide mapping and phosphoamino acid analysis revealed that phosphorylation at Ser(10) accounted for approximately 70% of the total phosphorylation of p27(Kip1), and the extent of phosphorylation at this site was approximately 25- and 75-fold greater than that at Ser(178) and Thr(187), respectively. The phosphorylation of p27(Kip1) was markedly reduced when the positions of Ser(10) and Pro(11) were reversed, suggesting that a proline-directed kinase is responsible for the phosphorylation of Ser(10). The extent of Ser(10) phosphorylation was markedly increased in cells in the G(0)-G(1) phase of the cell cycle compared with that apparent for cells in S or M phase. The p27(Kip1) protein phosphorylated at Ser(10) was significantly more stable than the unphosphorylated form. Furthermore, a mutant p27(Kip1) in which Ser(10) was replaced with glutamic acid in order to mimic the effect of Ser(10) phosphorylation exhibited a marked increase in stability both in vivo and in vitro compared with the wild-type or S10A mutant proteins. These results suggest that Ser(10) is the major site of phosphorylation of p27(Kip1) and that phosphorylation at this site, like that at Thr(187), contributes to regulation of p27(Kip1) stability."xsd:string |
