Cyclin I: Proteins and Enzymes

The protein encoded by the Cyclin gene belongs to the highly conserved cyclin family, whose members are characterized by adramatic 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 coordinationof each mitotic event. This cyclin shows the highest similarity with cyclin G. The transcript of this gene was foundto be expressed constantly during cell cycle progression. The function of this cyclin has not yet been determined.(provided by RefSeq)
