Cyclic AMP-Sensitive Ion Channels in Olfactory Receptor Cells

摘要

Membranes from rat olfactory epithelial homogenates were incorporated into planarbilayers by a tip-dipping method. Analysis of single-channel currents indicate the existence of a cation channel activated by the addition of adenosine 3',5' monophosphate (cAMP). The activity did not require exogenous ATP or GTP. The
