Cyclin B is a member of the cyclin family. Cyclin B is a mitotic cyclin. The amount of cyclin B (which binds to Cdk1) and the activity of the cyclin B-Cdk complex rise through the cell cycle until mitosis, where they fall abruptly due to degradation of cyclin B (Cdk1 is constitutively present). The complex of Cdk and … See more Cyclin B is necessary for the progression of the cells into and out of M phase of the cell cycle. At the end of S phase the phosphatase cdc25c dephosphorylates tyrosine15 and this activates the … See more Cyclin B plays in integral role in many types of cancer. Hyperplasia (uncontrolled cell growth) is one of the hallmarks of cancer. Because cyclin B is necessary for cells to enter mitosis and therefore necessary for cell division, cyclin B levels are often de … See more • Cyclin B1 • Cyclin B2 See more • Cyclin+B at the U.S. National Library of Medicine Medical Subject Headings (MeSH) • Drosophila Cyclin B - The Interactive Fly See more WebCdk1 is a small protein (approximately 34 kilodaltons), and is highly conserved. The human homolog of Cdk1, CDK1, shares approximately 63% amino-acid identity with its yeast …

WebCdk1, in complex with cyclin B (Cdk1/cyclin B), is a negative regulator of cytokinesis and Cdk1/cyclin B catalytic activity must be switched off to allow initiation of cytokinesis (Potapova et al., 2006). In early mitosis, Cdk1/cyclin B activity is high to promote assembly of the mitotic apparatus and chromosome alignment. WebApr 19, 2010 · Cyclin B–Cdk1 activity causes a general change in the transport machinery that triggers cyclin B–Cdk1 nuclear import.
