Receptor for tachykinin-like peptides. During late embryogenesis (stages 11-15), expressed in the brain and in a specific subset of neurons in each neuromere of the developing ventral ganglion. Expressed in the cortex of the adult brain, which contains the neuronal cell bodies. Expressed throughout development and in the adult. Highest level of expression observed during late embryogenesis. Belongs to the G-protein coupled receptor 1 family.
