Aspirin exerts its unique pharmacological effects by irreversibly acetylating a serine residue in the cyclooxygenase site of prostaglandin-H2-synthases (PGHSs). Despite the irreversibility of the inhibition, the potency of aspirin varies remarkably between cell types, suggesting that molecular determinants could contribute to cellular selectivity.

Two subtypes of the human cannabinoid receptor have been identified. The CB1 receptor is primarily distributed in the central nervous system, whereas the CB2 receptor is associated with peripheral tissue, including the spleen. These two subtypes are also distinguished by their ligand-binding profiles. The goal of this study was to identify critical residues(More)
The human cannabinoid receptor associated with the CNS (CB1) binds delta9-tetrahydrocannabinol, the psychoactive component of marijuana, and other cannabimimetic compounds. This receptor is a member of the seven transmembrane domain G protein-coupled receptor family and mediates its effects through inhibition of adenylyl cyclase. An understanding of the(More)
The human cannabinoid receptor CB1 functionally couples primarily to Gi-, but also to Gs-mediated pathways to modulate intracellular cyclic AMP (cAMP) levels. To probe the features of the receptor that may be involved in promoting interactions with one G protein type over another, we generated the L341A/A342L mutant CB1 receptor. The double mutation(More)
