Substance-K receptor is a protein that in humans is encoded by the TACR2 gene.This gene belongs to a family of genes that function as receptors for tachykinins. Receptor affinities are specified by variations in the 5′-end of the sequence. The receptors belonging to this family are characterized by interactions with G proteins and 7 hydrophobic transmembrane regions. This gene encodes the receptor for the tachykinin neuropeptide substance K also referred to as neurokinin A.
