Quaternary structure of the acetylcholine receptor

Nature. 1985 Jun 6-12;315(6019):474-7. doi: 10.1038/315474a0.

Abstract

The five membrane-spanning subunits of the acetylcholine receptor have been resolved in electron microscope images and are shown to lie at pentagonally symmetrical positions around the channel over a large fraction of their length. The channel consists of a wide synaptic portion and a narrow portion extending through the membrane into the interior of the cell.
