abstract：:A protein that binds vesamicol has been purified from a soluble fraction of the Torpedo electric organ homogenate that does not contain synaptic vesicles. The purified vesamicol-binding protein (VBP) has a molecular mass of 470 kDa composed of 30- and 24-kDa subunits. Chemical deglycosylation yielded a single, heterog...

abstract：:Neurons from the granular layer of the cerebellum express functional beta 2-adrenoreceptors (beta 2-ARs). We show that stimulation of beta 2-ARs with isoprenaline increases cyclic AMP (cAMP) production and stimulates transcription of genes containing the cAMP-responsive element (CRE; TGACGTCA). This effect is mediated...
