Enables chemoattractant activity involved in axon guidance and frizzled binding activity. Involved in nervous system development and stem cell development. Acts upstream of or within several processes, including animal organ development; blood vessel morphogenesis; and oxygen homeostasis. Located in cell surface. Is expressed in several structures, including central nervous system; early conceptus; future brain; genitourinary system; and sensory organ. Orthologous to human WNT7B (Wnt family member 7B).
