Enables tachykinin receptor activity. Involved in several processes, including hyperosmotic salinity response; positive regulation of uterine smooth muscle contraction; and response to alkaloid. Located in several cellular components, including dendrite membrane; neuronal cell body membrane; and nucleus. Used to study hypertension. Biomarker of visual epilepsy. Human ortholog(s) of this gene implicated in hypogonadotropic hypogonadism 11 with or without anosmia. Orthologous to human TACR3 (tachykinin receptor 3).
