Is an ortholog of human ANOS1 (anosmin 1). Exhibits heparan sulfate proteoglycan binding activity\; heparin binding activity\; and syndecan binding activity. Is involved in several processes, including embryo development\; embryonic morphogenesis\; and generation of neurons. Localizes to the cell surface. Is expressed in the excretory cell\; the nervous system\; the neuroblast\; and the reproductive system. Is used to study Kallmann syndrome. Human ortholog(s) of this gene are implicated in hypogonadotropic hypogonadism 1 with or without anosmia.
