Human G1 S-specific Cyclin-E1, CCNE1 ELI

G1/S-specific cyclin-E1 is a protein that in humans is encoded by the CCNE1 gene.

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.

Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mitotic event.
