Neurotensin receptor type 1 (NTSR1)

G-protein coupled receptor for the tridecapeptide neurotensin (NTS) (PubMed:8381365, PubMed:21725197, PubMed:23140271). Signaling is effected via G proteins that activate a phosphatidylinositol-calcium second messenger system.

Signaling leads to the activation of downstream MAP kinases and protects cells from apoptosis (PubMed:21725197). .
