Description:
Two different divalent cation-selective channels from Paramecium cilia were incorporated into planar lipid bilayers. Both channels were much more permeable to divalent than univalent cations, and one of them discriminated significantly among the divalent cations. The selectivity and voltage dependence of the latter channel are comparable to those of voltage-dependent calcium channels found in a variety of cells. A combined biochemical, biophysical, and genetic study of calcium channels is now possible.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ehrlich, B E -- Finkelstein, A -- Forte, M -- Kung, C -- GM 22714/GM/NIGMS NIH HHS/ -- GM 29210/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1984 Jul 27;225(4660):427-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6330895" target="_blank"〉PubMed〈/a〉
