CDK4-CCND2 Protein, Human (Active, sf9, GST, Flag, His),Human,Sf9 insect cells
CDK4 protein, acting as a Ser/Thr kinase in the cyclin D-CDK4 complex, critically regulates the G(1)/S transition by phosphorylating and inhibiting RB family members. This activity, specifically hypophosphorylation of RB1 during early G(1) phase, releases E2F and promotes transcription of genes that drive G(1) progression. CDK4-CCND2 Protein, Human (sf9, GST, Flag, His) is the recombinant human-derived CDK4-CCND2, expressed by Sf9 insect cells, with N-His, N-GST, N-Flag labeled tag.
