WebThe effects of insulin are initiated by its binding to a receptor, the insulin receptor (IR), present in the cell membrane. The receptor molecule contains an α- and β subunits. Two molecules are joined to form what is known as … WebThe insulin receptor comprises two extracellular α subunits and two transmembrane β subunits linked together by disulfide bonds. The binding of insulin to the α subunit induces a conformational change resulting in the autophosphorylation of several tyrosine residues in the β subunit (Van Obberghen et al., 2001).
