Instead, it plays important roles in the development of the central nervous system, and also helps to regulate synaptic function. CDK5 is activated by a ... WebG2 functions of A-CDK1 are the execution of checkpoint controls, discussed below. Levels of cyclin B build more slowly than the other cyclins, beginning in late G1 and only reaching appreciable levels in mid-G2, when it begins to replace cyclin A in complexes with CDK1.
