Abstract

Mutation of glutamic acid 282 of PPARα to glycine has been shown to result in an increased EC₅₀ for a wide variety of PPAR activating compounds. This has suggested that mutant receptor has a reduced ability to bind ligand. In this study we show that this mutation reduces the affinity of mPPARα and hPPARγ for the fluorescent fatty acid, cis-parinaric acid and that the mutant hPPARγ protein has a reduced affinity for the radiolabelled compound, SB236636. These data confirm the role of this glutamic acid in ligand binding and support recent crystal structure observations regarding a proposed novel mode of ligand entry into the PPAR ligand binding cavities.
