IGF-I receptor (IGF1R) mediates insulin-like growth factor effects, binding strongly to IGF1. Activation triggers PI3K-AKT/PKB and Ras-MAPK pathways, influencing cell survival, protein synthesis, and proliferation. IGF1R also signals through JAK/STAT, inhibiting JNK activation. Hybrid receptors show variable binding to IGF1 and insulin. IGF-I R Protein, Human (sf9, His-GST) is the recombinant human-derived IGF-I R protein, expressed by Sf9 insect cells , with N-His, N-GST labeled tag.
