The actions of GIP on the pancreatic beta cell are primarily of which among the following peptides? Correct Answer Incretin

Incretin, a gut-derived peptide that activates insulin secretion by setting elevated plasma glucose levels after ingestion of oral nutrients, is the key action of GIP on the pancreatic beta cell. GIP receptor knockout mice are viable but, after high-fat feeding, display reduced oral glucose tolerance and increased susceptibility to diabetes.

An in vitro translation system can synthesize peptides in all three reading frames of the RNA template. When 5' - UCUCUCUC-(UC)n-UCUCUCUC - 3' was used as the template in this in vitro translation system, the synthesized peptides contained 50% each of serine and leucine. When 5' - CCUCCUCCU-(CCU)n-CCUCCU - 3' was used as the template, the synthesized peptides contained 33.3% each of serine, leucine, and proline. Deduce the codon for proline.
