Predicted to enable several functions, including anaphase-promoting complex binding activity; histone deacetylase binding activity; and protein C-terminus binding activity. Involved in positive regulation of synapse maturation and positive regulation of synaptic plasticity. Acts upstream of or within mitotic sister chromatid cohesion; mitotic spindle assembly; and regulation of meiotic nuclear division. Predicted to be located in several cellular components, including centrosome; nucleoplasm; and perinuclear region of cytoplasm. Predicted to be part of anaphase-promoting complex. Is expressed in several structures, including brain; early conceptus; female reproductive system; hemolymphoid system; and trigeminal ganglion. Orthologous to human CDC20 (cell division cycle 20).
