Structural requirements for mutational lutropin/choriogonadotropin receptor activation.

Different activation mechanisms of glycoprotein hormone receptors, which are members of the G protein-coupled receptor superfamily, have been proposed. For example, the large ectodomain of glycoprotein hormone receptors may function as an inverse agonist keeping the transmembrane domain in an inactive conformation. To provide support for this hypothesis, we have generated different lutropin/cho...

Structural requirements of bitter taste receptor activation.

An important question in taste research is how 25 receptors of the human TAS2R family detect thousands of structurally diverse compounds. An answer to this question may arise from the observation that TAS2Rs in general are broadly tuned to interact with numerous substances. Ultimately, interaction with chemically diverse agonists requires architectures of binding pockets tailored to combine fle...

Structural requirements for the transmembrane activation of the insulin receptor kinase.

Tetrameric insulin holoreceptor (alpha 2 beta 2) was reduced with dithiothreitol into alpha beta dimers such that they maintain up to 50% of insulin binding at tracer ligand concentrations. Scatchard analysis of insulin binding to dimers revealed that they had a reduced affinity for ligand by a factor of 3-6 compared to holoreceptor, whereas the maximum number of high affinity binding sites was...

Structural requirements of platelet chemokines for neutrophil activation.

Using recombinantly expressed proteins and synthetic peptides, we examined the structural/functional features of the platelet chemokines, neutrophil-activating peptide-2 (NAP-2) and platelet factor 4 (PF4); that were important in their activation of neutrophils. Previous studies with the chemokine interleukin-8 (IL-8) had shown that the N-terminal region preceding the first cysteine residue was...

Structural Requirements for Pairing

The class II antigens ofthe human MHC are cell surface heterodimers composed of noncovalently linked 35-kD a chains and 29-kD (3 chains . These antigens are present on macrophages, B lymphocytes, and other APC (for review, see reference 1). Class II antigens are capable of binding immunogenic peptides and thereby serve as ligand for the TCR (2, 3) . Recent experiments have demonstrated that cla...
