Photoaffinity labeling of plasma proteins.
Photoaffinity labeling is a powerful technique for identifying a target protein. A high degree of labeling specificity can be achieved with this method in comparison to chemical labeling. Human serum albumin (HSA) and α1-acid glycoprotein (AGP) are two plasma proteins that bind a variety of endogenous and exogenous substances. The ligand binding mechanism of these two proteins is complex. Fatty...
متن کاملPhotoaffinity labeling of retinoic acid-binding proteins.
Retinoid-binding proteins are essential mediators of vitamin A function in vertebrate organisms. They solubilize and stabilize retinoids, and they direct the intercellular and intracellular trafficking, transport, and metabolic function of vitamin A compounds in vision and in growth and development. Although many soluble retinoid-binding proteins and receptors have been purified and extensively...
متن کاملPhotoaffinity labeling of insulin receptor of rat adiopocyte plasma membrane.
A photosensitive insulin derivative was synthesized by reacting radioactive iodinated bovine insulin with N-hydroxysuccinimide ester of 4-azidobenzolic acid. The photo-sensitivity and specificity of this insulin derivative were established by its covalent nonspecific cross-link to albumin and its covalent specific cross-link to the heavy and light chains of anti-insulin immunoglobulin. Plasma m...
متن کاملThe mechanism of photoaffinity labeling.
Photoaffinity labeling is a recently introduced method for covalently binding chemical tags to the active sites of protein molecules, which is potentially capable of very great specificities of labeling. A labeling reagent is used that is converted by photolysis to an extremely reactive intermediate. According to the expected mechanism, the reagent molecules that are specifically and reversibly...
متن کاملPhotoaffinity Labeling of Bovine Rhodopsin
Photoaffinity labeled (3diazoacetoxy)-9-CC-retinal (1) and (9-methylenediazoacetoxy)9-c&retinal (2) were synthesized and bound to bovine opsin to obtain visual pigment analogs having absorption maxima at 465 and 460 nm respectively. Binding studies established that synthetic retinals 1 and 2 bind to the natural binding site and that the integrity of the diazoacetoxy photoaffinity label is prese...
