Cyclin D3 Explained

G1/S-specific cyclin-D3 is a protein that in humans is encoded by the CCND3 gene.[1]

Function

The protein encoded by this gene belongs to 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. This cyclin forms a complex with and functions as a regulatory subunit of CDK4 or CDK6, whose activity is required for cell cycle G1/S transition. This protein has been shown to interact with and be involved in the phosphorylation of tumor suppressor protein Rb. The CDK4 activity associated with this cyclin was reported to be necessary for cell cycle progression through G2 phase into mitosis after UV radiation.[2]

Clinical significance

Mutations in CCND3 are implicated in cases of breast cancer.[3]

Interactions

Cyclin D3 has been shown to interact with:
