Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	This is a receptor for the tachykinin neuropeptide neuromedin-K (neurokinin B). It is associated with G proteins that activate a phosphatidylinositol-calcium second messenger system. The rank order of affinity of this receptor to tachykinins is: neuromedin-K > substance K > substance P.
Subcellular location	Cell membrane; Multi-pass membrane protein.
Post-translational modification	The anchoring of this receptor to the plasma membrane is probably mediated by the palmitoylation of a cysteine residue.
Sequence similarities	Belongs to the G-protein coupled receptor 1 family.
