Predicted to enable cell adhesion molecule binding activity. Predicted to be involved in several processes, including actin cytoskeleton reorganization; cellular response to retinoic acid; and positive regulation of canonical Wnt signaling pathway. Predicted to act upstream of or within several processes, including animal organ development; axis elongation; and morphogenesis of an epithelium. Predicted to be located in membrane. Predicted to be active in cell-cell junction and plasma membrane. Orthologous to human PTK7 (protein tyrosine kinase 7 (inactive)). [provided by Alliance of Genome Resources, Apr 2022]
