WebExtracellular positive (mitogenic) and inhibitory cues are sensed in cells through fluctuating levels of cyclins. These proteins are required to activate cyclin-dependent kinases (Cdks). Cyclin D-Cdk4/6 complexes form in G1, cyclin E-Cdk2 complexes act at G1-S, cyclin A-Cdk2 complexes drive S, and cyclin B-Cdk1 complexes drive M. WebApr 13, 2024 · Nevertheless, the fluctuations in the RMSD values of curcumin were not related to the KK or KE forms as the RMSD values of curcumin for SIK3-O_KK-1 and SIK3-O_KE-1 were 1.98 ± 0.31 Å and 1.98 ± 0.25 Å, respectively. Simultaneously, we observed that the KE form of curcumin may cause more fluctuations for curcumin than the KK form.
