10.1210/endo.140.4.6661 81

INSR B -IGF1R hybrids comprises up to 30% of INSR and IGF-I receptors in muscle due to high expression of both and this hybrid predominantly responds to IGF-I (less to insulin) and explains the important role of IGF-I in growth and metabolism in skeletal muscle

Mechanical stress can damage the tripeptide (although as a smaller molecule its mechanical sensitivity is lower than that of large peptides)

Knockdown of the IGF1 leads to a reduction in m and alterations in mitochondrial morphology in ALS mice (Wen et al., 2019)
