Abstract

The Anaphase Promoter Complex (APC) is a multiprotein complex - an E3 ubiquitin ligase - involved in ubiquitin-dependent proteolysis of cell cycle regulatory proteins, which include the destruction of mitotic cyclins during the transition of metaphase to anaphase. Identification of the complete set of genes encoding the subunits of the APC in Arabidopsis, suggests that the basic processes controlled by ubiquitin-mediated proteolysis in plants are similar to those of other organisms. However, results from several groups indicate that the APC has other specific functions in the regulation of plant development. (AU)
