Among them, CYCD4;2 is unique in the amino acid sequence; namely, it lacks the Rb-binding motif and the PEST sequence that are conserved in CYCDs. Here, we have shown that CYCD4;2 suppressed G1 cyclin mutations in yeast and formed a kinase complex with CDKA;1, an ortholog of yeast Cdc28, in insect cells. Hypocotyl explants of CYCD4;2 over-expressing plants showed faster induction of calli than wild-type explants on a medium containing lower concentration of auxin. These results suggest that CYCD4;2 has a promotive function in cell division by interacting with CDKA;1 regardless of the unusual primary sequence.
