The insulin receptor (IR) and the homologous Type 1 insulin-like growth factor receptor (IGF-1R) are cell-surface tyrosine kinase receptors that effect signaling within the respective pathways of glucose metabolism and normal human growth. While ligand binding to these receptors is assumed to result …

intra-molecular interactions unique for each receptor [19, 20]. Ligand-induced dimerization releases this cis-autoinhibition. FGFR, IR, and IGF-1R receptors are autoinhibited by the activation loop, which directly con-tacts the active site of the kinase and disrupts ATP and substrate binding [21, 22]. KIT and Eph receptors are

Left, TNF (soluble and membrane-bound) binding to TNFR1 results in TNFR1 trimerisation. Middle, FasL can bind Fas to initiate apoptosis. Decoy receptors, DcR and soluble DcR3 contain extracellular ligand-binding domains but do not contain an intracellular death domain, compet-ing with Fas to bind FasL and intra-molecular interactions unique for each receptor [19, 20].

This assay Ligand binding breaks the tether, allowing the dimerization arm of domain II to interact with a second ligand-bound receptor molecule (Figure 2D). As with KIT ( Figure 2 B), the membrane-proximal domain of EGFR (domain IV) also appears to make contacts across the dimer interface ( Burgess et al., 2003 ), which may orient the dimers in the Ligand-Binding Domain • often has a large EXTRACELLULAR ligand-binding domain allowing for easy access and activation to the receptor. Transmembrane Domain • composed of a series of hydrophobic amino acids (reminder: inner membrane is lipophilic/hydrophobic) that tethers the receptor to the cell membrane. However, many receptors involve three or more cell surface components, and the effect of this additional complexity on how ligand binding is quantitatively coupled to receptor activation and signaling is not well understood.

Ligand binding to one subtype of integrins can affect the activation state of another integrin subtype on the same cell, by modulating the ligand-binding affinity and/or avidity of that integrin. For example, outside-in signaling through ligand binding of α 4 β 1 integrin can affect α L β 2 -dependent lymphocyte adhesion and migration by regulating signaling through α L β 2 .

2000-11-20 2015-07-16 Ligand binding to its particular receptor was thought to trigger internalization of the recep- tor-ligand complex into endosomes, with subse- quent degradation in lysosomes. Figure 28.17 shows that dimerization can take several forms (for review see 2898).The most common is that a ligand binds to one or to both monomers to induce them to dimerize (2905).A variation is that a dimeric ligand binds to two monomers to bring them together (2902).In the case of the insulin receptor family, the ligand binds to a dimeric receptor (which is stabilized by extracellular 2012-11-06 Relative Contributions of Desolvation, Inter- and Intramolecular Interactions to Binding Affinity in Protein Kinase Systems PETER A.
