Insulin: The Receptor and Signaling Pathways01:28

Insulin: The Receptor and Signaling Pathways

Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but this inhibition is released...

Area of Science:

  • Endocrinology and Molecular Biology
  • Hormone signaling and receptor interactions
  • Bioinformatics and database development

Background:

  • Insulin-like growth factors (IGFs) and insulin are critical hormonal regulators of eukaryotic growth, development, and metabolism.
  • Perturbations in IGF and insulin signaling pathways are linked to various developmental and survival abnormalities.
  • Understanding ligand-receptor interactions is key to elucidating biological effects and developing therapeutics.

Purpose of the Study:

  • To create a centralized, searchable repository for insulin-like growth factor (IGF) and insulin analogue data.
  • To compile and present receptor binding affinities for engineered IGF and insulin analogues.
  • To facilitate research on IGF and insulin-related diseases through accessible data.

Main Methods:

  • Development of a web-based, curated database named the Insulin-like Growth Factor Mutation Database (IGFmdb).
  • Inclusion of publicly accessible receptor binding data for IGF-I, IGF-II, and insulin analogues.
  • Annotation of ligand analogues with their corresponding receptor binding affinities.

Main Results:

  • The IGFmdb currently contains binding data for 67 IGF-II analogues, 67 IGF-I analogues, and 32 insulin analogues.
  • Data includes information on engineered analogues and species homologues.
  • The database is accessible online at http://www.adelaide.edu.au/igfmutation.

Conclusions:

  • The IGFmdb provides a valuable resource for researchers studying IGF and insulin signaling.
  • Future updates will expand the database to include all publicly accessible IGF-I analogues and IGF-binding protein (IGFBP) affinities.
  • This resource supports the design of therapeutic agents for IGF and insulin-related disorders.
