C;-!- FUNCTION: AFTER BINDING ACETYLCHOLINE, THE ACHR RESPONDS BY AN
C;EXTENSIVE CHANGE IN CONFORMATION THAT AFFECTS ALL SUBUNITS AND
C;LEADS TO OPENING OF AN ION-CONDUCTING CHANNEL ACROSS THE PLASMA
C;MEMBRANE.
C;-!- SUBUNIT: NEURONAL ACHR SEEMS TO BE COMPOSED OF TWO DIFFERENT
C;TYPE OF SUBUNITS: ALPHA AND NON-ALPHA (BETA).
