About IGF-1 LR3
IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a synthetic analogue of Insulin-like Growth Factor-1, modified by substitution of Glutamine for Arginine at position 3 and the addition of a 13-amino acid extended N-terminal sequence. These modifications reduce binding affinity to IGF-binding proteins (IGFBPs) for research applications requiring extended stability.
Primary areas of investigation
- IGF1R receptor signalling research
- PI3K/Akt cascade studies
- MAPK/ERK pathway investigation
- Tyrosine kinase signalling models
- Cell proliferation research
- Fibroblast cell line studies
Mechanism
Research into IGF-1 LR3 examines its activation of the IGF-1 receptor (IGF1R), a transmembrane tyrosine kinase, in experimental cell models. The peptide is investigated for its role in PI3K/Akt and MAPK/ERK signalling cascade research. Due to its engineered reduced affinity for IGFBPs, the analogue allows research into extended signalling duration in controlled systems.
