Predicted to enable Wnt-protein binding activity. Predicted to be involved in positive regulation of canonical NF-kappaB signal transduction. Predicted to act upstream of or within G protein-coupled receptor signaling pathway; Wnt signaling pathway; and cell surface receptor protein tyrosine kinase signaling pathway. Predicted to be part of receptor complex. Predicted to be active in axon and plasma membrane. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 108. Orthologous to human ROR1 (receptor tyrosine kinase like orphan receptor 1).
