Neurotensin receptor type 1

Gene

Ntsr1

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

G-protein coupled receptor for the tridecapeptide neurotensin (NTS) (PubMed:23051748, PubMed:24453215, PubMed:26205105). 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 against apoptosis (By similarity).By similarity4 Publications
