Description:
Human cyclin E, originally identified on the basis of its ability to function as a G1 cyclin in budding yeast, associated with a cell cycle-regulated protein kinase in human cells. The cyclin E-associated kinase activity peaked during G1, before the appearance of cyclin A, and was diminished during exit from the cell cycle after differentiation or serum withdrawal. The major cyclin E-associated kinase in human cells was Cdk2 (cyclin-dependent kinase 2). The abundance of the cyclin E protein and the cyclin E-Cdk2 complex was maximal in G1 cells. These results provide further evidence that in all eukaryotes assembly of a cyclin-Cdk complex is an important step in the biochemical pathway that controls cell proliferation during G1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koff, A -- Giordano, A -- Desai, D -- Yamashita, K -- Harper, J W -- Elledge, S -- Nishimoto, T -- Morgan, D O -- Franza, B R -- Roberts, J M -- New York, N.Y. -- Science. 1992 Sep 18;257(5077):1689-94.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Basic Sciences, Fred Hutchinson Cancer Research Center, Seattle, WA 98104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1388288" target="_blank"〉PubMed〈/a〉
