The Molecular Structure and Synthesis of IGF1

The IGF1 gene is transcribed into mRNA, which is then translated into a precursor protein.作者：A Chuard·2025·被引用次数：2—Viral insulin-like peptides activate human insulin and IGF-1 receptor signaling: A paradigm shift for host-microbe interactions. Proc. Natl ... This precursor includes a signal peptide at the 5' end, which is vital for directing the protein to its correct cellular location and is subsequently cleaved offIGF-I Receptor beta Blocking Peptide #1525. The initial translation product of IGF-I mRNA contains an unusual 48-amino acid signal peptide. This process results in an immature IGF-1 peptide, which undergoes further processing. The mature IGF1 peptide is a relatively small protein, measuring approximately 7.65 kDa and consisting of about 70 amino acids. It exhibits significant sequence homology with insulin, hence its name.Insulin-like growth factor 1 (IGF-1) is a small (7.65 kDa) growth factor that interacts with both the IGF-1 receptor and the insulin receptor to control cell ...

Interestingly, the IGF1 gene splicing and posttranslational modifications can lead to different protein isoforms. These isoforms differ primarily in the structure of their extension peptides, specifically the E-peptides found at the carboxy-terminal end, and their overall length. The IGF-I E peptide, also known as mechano-growth factor (MGF), is particularly noteworthy. This peptide signaling component is upregulated in exercised and damaged muscles and is believed to play a neuroprotective role against ischemia.作者：XT Song·2021·被引用次数：6—Insulin-like growth factor 1 (IGF1), also known as somatomedin C,is essential for the regulation of animal growth and development. The intrinsically disordered E-domains of these peptides are known to regulate the IGF1 signaling cascade.

The IGF1 Signaling Pathway: Mechanism of Action

The primary mechanism by which IGF1 exerts its effects is through binding to its specific receptor, the IGF-1 receptor (IGF-IR). This receptor is a tyrosine kinase type I receptor作者：B Gorai·2022·被引用次数：4—In contrast,IGF1 plays a critical role in development and growth of tissues and organs. The processes underlying normal growth, development, .... Upon binding of IGF1, the IGF-IR becomes activated, initiating a cascade of intracellular signaling events. This pathway is critical for promoting cell proliferation, growth, and survival.

While IGF1 primarily signals through IGF-IR, it shares structural similarities with insulin and can also interact with the insulin receptor. Conversely, IGF-II, another member of the insulin-like growth factor family, can signal through IGF-IR and also the IGF-II/Mannose-6-phosphate receptor.

Research has also uncovered the intriguing role of viral insulin-like peptides (VILPs). These viral insulin-like peptides have been found to activate human insulin and IGF-1 receptor signaling.作者：BK Brisson·2012·被引用次数：69—We find that E-peptide signaling, mitogenic, and motogenic effects are dependent upon IGF-IR. We propose that the E-peptideshave little independent activity. In fact, some VILPs, such as scLCDV1-VILP, act as natural peptides with specific antagonist properties on IGF1R signaling, offering potential new tools for developing hormonal analogues. Studies have shown that viral insulin-like peptides can inhibit IGF-1 receptor activity, demonstrating a complex interplay between viral and host signaling pathways.
