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.
Studies of similar genes in chick and Drosophila suggest that this
cyclin may associate with CDC2 and CDK2 kinases, and be required
for proper spindle reorganization and restoration of the interphase
nucleus. Two transcript variants encoding different isoforms have
been found for this gene.
