Enables Wnt-activated receptor activity; Wnt-protein binding activity; and frizzled binding activity. Involved in nervous system development. Acts upstream of or within generation of neurons; negative chemotaxis; and skeletal system morphogenesis. Located in cytoplasm; nucleus; and plasma membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system; and sensory organ. Orthologous to human RYK (receptor like tyrosine kinase).
