NK4R is a putative Tachykinin Receptor with sequence similarities to the neuromedin K receptor. It was initially thought to be an opioid receptor and is antagonized by the opioid peptide dynorphin. However, NK4R is activated by the tachykinin neurokinin B.
Gene Name: Neuromedin K Receptor-Like Protein (NK4R)
Family/Subfamily: GPCR; Tachykinin
