Insulin receptor alpha and beta subunits

NettetA cell surface receptor for insulin. It comprises a tetramer of two alpha and two beta subunits which are derived from cleavage of a single precursor protein. The receptor contains an intrinsic tyrosine KINASE domain that is located within the beta subunit. Activation of the receptor by insulin results in numerous metabolic changes including ...

Autophosphorylation within insulin receptor beta-subunits can …

NettetThe 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).

(1997) identified a second subunit of the IKK complex, called IKK-beta. IKK-beta is 50% identical to IKK-alpha and contains the kinase domain, a leucine zipper, and a helix-loop-helix. NettetThe insulin receptor is a hetero-tetrameric glycoprotein consisting of 2 extracellular α and 2 transmembrane β subunits linked together by disulfide bonds. It is oriented across the cell membrane as a heterodimer (Fig. 19.3). The α subunits carry insulin binding sites, while the β subunits have tyrosine protein kinase activity. manitoba notary public application
