Predicted to enable peptidyl-dipeptidase inhibitor activity. Involved in mesenchymal cell proliferation involved in ureteric bud development. Acts upstream of or within several processes, including animal organ development; positive regulation of transport; and regulation of signal transduction. Located in lysosome and plasma membrane. Is anchored component of plasma membrane. Is expressed in several structures, including branchial arch; future brain; lower jaw; reproductive system; and urinary system. Used to study Simpson-Golabi-Behmel syndrome type 1. Human ortholog(s) of this gene implicated in Simpson-Golabi-Behmel syndrome type 1; hepatocellular carcinoma; and nephroblastoma. Orthologous to human GPC3 (glypican 3). [provided by Alliance of Genome Resources, Apr 2022]
