Cyclin B2 Proteins and Enzymes

Cyclin B2 (also CCNB2 and G2/mitotic-specific cyclin-B2) is a 45-46 kDa member of the Cyclin AB subfamily, cyclin family of proteins. It is widely expressed and associates with CDK1 providing substrate specificity to a phosphorylating complex. A phosphorCDK1:Cyclin B2 complex is associated with the Golgi apparatus, where it contributes to Golgi fragmentation during mitosis. It is also possible that Cyclin B2 can substitute for Cyclin B1 during the early stages of mitosis. Human Cyclin B2 is 398 ...
