About Insulin: What It Is, How It Works, and More

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). WebThis insulin is the signal for a rapid transfer of GLUT4 in muscle and adipose cells to the cell membranes of these cells, bringing about an increased glucose transport into the cells. Simultaneously, insulin reduces the liver’s metabolism of the sugar. Sign in to download full-size image Figure 4.10.
