Predicted to enable cyclin-dependent protein serine/threonine kinase inhibitor activity. Predicted to be involved in negative regulation of epithelial cell proliferation and negative regulation of mitotic cell cycle. Predicted to act upstream of or within regulation of cell cycle. Predicted to be located in nucleus. Is expressed in ectoderm; mesoderm; musculoskeletal system; nervous system; and visual system. Human ortholog(s) of this gene implicated in several diseases, including Beckwith-Wiedemann syndrome; IMAGe syndrome; hematologic cancer (multiple); hyperinsulinism; and multiple endocrine neoplasia type 4. Orthologous to several human genes including CDKN1C (cyclin dependent kinase inhibitor 1C).
