Peptides influence growth hormone pathways, while testosterone impacts libido, strength, energy, mood, and muscle density through a separate hormonal system
Indeed, tyrosine-972 in the NPEY motif of IR (numbering relative to human IR-B or +exon 11 isoform), which is phosphorylated following ligand stimulation, serves as a docking site for proteins with a PTB domain, such as IRS-1 and Shc, and mutation of this residue markedly decreases phosphorylation of these receptor substrates and activation of downstream signaling (16, 17)
