cwn-1 encodes one of five C. elegans Wnt signaling ligands; during embryogenesis cwn-1 likely functions as a downstream target of the PAL-1 homeodomain protein in the regulatory network that specifies cell fates in the C lineage that gives rise to ectodermal and muscle tissue; consistent with this role, loss of cwn-1 activity via RNAi results in rare larval tail defects that may result, in part, from abnormal morphogenesis of C lineage descendants; a cwn-1 reporter is expressed in C and D muscle cells, as well as in two posterior C ectodermal cells; cwn-1 mRNA is detectable at all developmental stages, with highest levels of expression seen in embryonic stages.
Enables receptor tyrosine kinase binding activity. Involved in several processes, including neuroblast migration; neuron migration; and positive regulation of axon guidance. Predicted to be located in extracellular space. Expressed in several structures, including CAN; hypodermal cell; intestine; muscle cell; and somatic nervous system. Human ortholog(s) of this gene implicated in Mullerian aplasia and hyperandrogenism and endometrial carcinoma. Is an ortholog of human WNT4 (Wnt family member 4).

Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
