WebCyclin 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 … WebTwo B-type cyclins, B1 and B2, have been identified in mammals. Proliferating cells express both cyclins, which bind to and activate Cdk1. Experiments with knockout mice demonstrated that the two B-type cyclins have distinct roles. Cyclin B2 knockout mice develop normally and did not display any obvious abnormalities, except reduced body size.

WebCyclin B1, a key component in the control of cell cycle progression from G2 to M phase, has been implicated in the tumorigenesis and the development of malignancy. The amount of cyclin B1 protein in ESSC is considerably higher than in normal adjacent tissues. WebMar 2, 1999 · Cyclin B1 is the regulatory subunit of the cdc2 kinase and is a protein required for mitotic initiation. The ability of p53 to control mitotic initiation by regulating intracellular cyclin B1 levels suggests that the cyclin B-dependent G 2 checkpoint has a role in preventing neoplastic transformation.
