Facts about Cyclin-dependent kinase 2.
Acts in the G1-S transition to advertise the E2F transcriptional program and the initiation of DNA synthesis, and modulates G2 development; controls the timing of entry into mitosis/meiosis by controlling the subsequent activation of cyclin B/CDK1 by phosphorylation, and coordinates the activation of cyclin B/CDK1 in the centrosome and in the nucleus. Activity of CDK2 is maximal during S phase and G2; activated by interaction with cyclin E during the first stages of DNA synthesis to allow G1-S transition, and then activated by cyclin A2 (cyclin A1 in germ cells) during the late stages of DNA replication to induce the transition from S phase to mitosis, the G2 phase.

Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Nucleus, Cajal body. Cytoplasm. Endosome. Localized at the centrosomes in late G2 phase after separation of the centrosomes but before the start of prophase. Nuclear-cytoplasmic trafficking is mediated during the inhibition by 1,25-(OH)(2)D(3).
