Activation of the insulin receptor by an insulin mimetic peptide ...

NettetWhen the pathway is activated by insulin, insulin receptor substrate 1 (IRS-1) transcription is down-regulated, in a negative feedback loop via mTORC1 and S6K1 activation. S6K1 is also able to phosphorylate IRS-1 at multiple serine residues, preventing binding to RTKs. NettetInsulin binds to the alpha subunit of the insulin receptor on the target cells, changing the conformation of the beta subunit and thereby activating tyrosine kinase. This activity evokes auto-phosphorylation of …
