Inactive tyrosine kinase involved in the Wnt signaling pathway. Component of both the non-canonical (also known as the Wnt/planar cell polarity signaling) and the canonical Wnt signaling pathways. Functions in cell adhesion, cell migration, cell polarity, proliferation, actin cytoskeleton reorganization and apoptosis. Has a role in embryogenesis, epithelial tissue organization and angiogenesis. Does not bind ATP (PubMed:24107129, PubMed:32619402). {ECO:0000269|PubMed:18471990, ECO:0000269|PubMed:20558616, ECO:0000269|PubMed:20837484, ECO:0000269|PubMed:21103379, ECO:0000269|PubMed:21132015, ECO:0000269|PubMed:24107129, ECO:0000269|PubMed:32619402}. This is the function of ENSG00000112655 (PTK7, protein tyrosine kinase 7 (inactive)).
