* Information From OMIM

Description: Cyclins are important in regulating the cell cycle through their formation of enzymatic complexes with various cyclin-dependent kinases. The D type cyclins complex with CDK4 (OMIM:123829) and CDK6 (OMIM:603368) to govern progression through the G1 phase of the cell cycle and later are involved with inactivating phosphorylation of the RB1 protein (OMIM:614041), which results in release of RB1-associated transcription factors that are needed for entry into S phase (Okuda et al., 1995). The activity of the cyclin D-dependent kinases is, in part, controlled by inhibitors such as the INK4 family, which includes INK4a (CDKN2A; OMIM:600160), 4b (CDKN2B; OMIM:600431), 4c (CDKN2C; OMIM:603369), and 4d (CDKN2D). INK4a has been shown to act by competing with CDK4 and CDK6 and functions as a tumor suppressor in a variety of cancers.
