Substance-K receptor is a protein that in humans is encoded by the TACR2 gene.[4]

Function

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.[4]

Selective Ligands

Several selective ligands for NK2 are now available, and although most of the compounds developed so far are peptides, one small-molecule antagonist Saredutant is currently in clinical trials as an anxiolytic and antidepressant.
