Background: Somatostatin regulates gut function via neuronal somatostatin receptors. Results: Somatostatin susceptibility to degradation by endosomal endothelin-converting enzyme 1 (ECE-1) defines receptor function. Conclusion: ECE-1 regulates the duration of somatostatin receptor signaling and trafficking. Significance: Therapeutic somatostatin analogs are ECE-1-resistant, which underlies their prolonged actions.
