Predicted to enable cyclin binding activity; cyclin-dependent protein serine/threonine kinase inhibitor activity; and identical protein binding activity. Predicted to be involved in negative regulation of cell population proliferation and negative regulation of cyclin-dependent protein serine/threonine kinase activity. Predicted to act upstream of or within positive regulation of apoptotic signaling pathway. Located in cytoplasm. Orthologous to human INCA1 (inhibitor of CDK, cyclin A1 interacting protein 1).
