Background: IGF-I/IGF-1
IGF-1 (IGF-I, insulin-like growth factor-1 or somatomedin C) is a secreted factor that circulates in complex with IGFBP-3 or IGFBP-5 with ALS. It signals through dimeric IGF1R, dimeric Insulin R, or a heterodimer of the two receptors.
Long Name
Insulin-like Growth Factor I/Insulin-like Growth Factor 1
Alternate Names
