Predicted to enable cyclin-dependent protein serine/threonine kinase regulator activity. Involved in several processes, including mitotic G2 DNA damage checkpoint signaling; negative regulation of apoptotic process; and syncytium formation. Located in several cellular components, including dendrite; neuronal cell body; and perinuclear region of cytoplasm. Orthologous to human CCNG1 (cyclin G1).
