Symbol/Gene Name:  TACR1

Alias:  Substance-P receptor,SPR,NK-1 receptor,NK-1R,Tachykinin receptor 1

Uniprot: P25103

Background: This is a receptor for the tachykinin neuropeptide substance P. It is probably associated with G proteins that activate a phosphatidylinositol-calcium second messenger system. The rank order of affinity of this receptor to tachykinins is: substance P > substance K > neuromedin-K.
