WebJun 16, 2024 · We performed in vitro phosphorylation experiments with human cyclin E-Cdk2, cyclin A-Cdk2, and cyclin B-Cdk1 using similar minimal model substrates as above (Figure 2 D). First, to assess the importance of the positive charge at −2 position from L in RxLxF, we used a motif with −2E from Cdc6 (P E K L Q F ). WebWe have analyzed E2F-1 phosphorylation and its interaction with cyclin A/CDK2 complexes both in vivo and in vitro. In vitro, E2F-1 formed a stable complex with cyclin …
