The Structural Determinants of Insulin-Like Peptide 3 Activity

Insulin-like peptide 3 (INSL3) is a hormone and/or paracrine factor which is a member of the relaxin peptide family. It has key roles as a fertility regulator in both males and females. The receptor for INSL3 is the leucine rich repeat (LRR) containing G-protein coupled receptor 8 (LGR8) which is now known as relaxin family peptide receptor 2 (RXFP2). Receptor activation by INSL3 involves bindi...

Structural determinants for activity of glucagon-like peptide-2.

Glucagon-like peptide-2 (GLP-2) is a 33 amino acid gastrointestinal hormone that regulates epithelial growth in the intestine. Dipeptidylpeptidase IV cleaves GLP-2 at the position 2 alanine, resulting in the inactivation of peptide activity. To understand the structural basis for GLP-2 action, we studied receptor binding and activation for 56 GLP-2 analogues with either position 2 substitutions...

Study of the insulin-like peptide 3 in human platelets

The insulin-like 3 peptide (INSL3) is autocrine/paracrine insulin-related hormone with a size of approximately 6kDa [1]. It mediates through a leucine rich G-coupled receptor named LGR8. INSL3 is mainly expressed in human Leydig cells and is directly responsible for migration of the testis during the pre-natal period in male development. [2] INSL3 mRNA has recently been verified in human platel...
