Predicted to enable patched binding activity. Involved in several processes, including neuron projection development; osteoblast proliferation; and positive regulation of vascular associated smooth muscle cell migration. Located in several cellular components, including growth cone; neuronal cell body; and postsynaptic density. Used to study Barrett's esophagus; esophagus adenocarcinoma; and middle cerebral artery infarction. Biomarker of ocular hypertension; pancreatitis; pre-malignant neoplasm; and visual epilepsy. Human ortholog(s) of this gene implicated in basal cell carcinoma; hepatocellular carcinoma; pancreatic cancer; and pancreatic ductal carcinoma. Orthologous to human SMO (smoothened, frizzled class receptor). [provided by Alliance of Genome Resources, Apr 2022]
