RYK (related to tyrosine (Y) kinase; also H-RYK) is a 70-90 kDa, atypical member of the tyrosine protein kinase family. It is a type I transmembrane glycoprotein that binds Wnt, and forms a Wnt receptor complex with frizzled. In this capacity, it serves as a link between Wnt and Dishevelled. Human RYK is 604 amino acids (aa) in length (SwissProt Accession # P34925). It contains a 25 aa signal sequence and a 199 aa extracellular region (aa 26-224) that shows one WIF-1-like domain (aa 63‑191). The cytoplasmic region possesses a nonfunctional Ser/Thr protein kinase domain (aa 327-600). One isoform exists that shows a 31 aa substitution between aa’s 18-46. Over aa 47-224, human RYK is 94% aa identical to mouse RYK.
