摘要: G1 cyclins control the to S phase transition in budding yeast, Saccharomyces cerevisiae. Cyclin E was discovered course of a screen for human complementary DNAs that rescue deficiency cyclin function yeast. The amounts both protein and an associated kinase activity fluctuated periodically through cell cycle; were maximal late early phases. E-associated correlated with appearance complexes containing cyclin-dependent Cdk2. Thus, E-Cdk2 complex may constitute G1-S phase-specific regulatory kinase.
