簡要描述：Cyclin B2 belongs to a the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK kinases. Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mitotic event. Cyclin B2 has been shown to be expressed in testis and brain, as well as in several leukemic cell lines, and is thought to primarily function in th
