Calcium-activated protein for secretion (CAPS) is proposed to play an essential role in Ca2+-regulated dense-core vesicle exocytosis in vertebrate neuroendocrine cells. Here we report the cloning, mutation, and characterization of the Drosophila ortholog (dCAPS). Null dCAPS mutants display locomotory deficits and complete embryonic lethality. The mutant NMJ(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)
