## TL;DR

SSTR3 (Somatostatin receptor type 3) is a gene. The public catalogues list it as a drug target, and an approved or late-stage drug is recorded against it. Tied to Neuroendocrine tumours.

## Summary

Receptor for somatostatin-14 and -28. This receptor is coupled via pertussis toxin sensitive G proteins to inhibition of adenylyl cyclase.

Open Targets scores its association with cancer at 0.56 (direct and indirect evidence; datatypes literature 0.50, genetic association 0.00, clinical 0.90).
