aminoacid sequence of subunit alpha of neuronal nAch receptors

[rcamsonn at hgmp.mrc.ac.uk]

The alpha subunit of nAchR is known to have 2 binding sites. One is dedicated 
to its activation/inactivation by both agonist and antagonist (competitive
antagonist) and another for its regulation owing to the specific binding 
of its non competitive antagonist represented by a chemical molecule called 
Mecamylamine.
I'd like to know the precise aminoacid sequences to which both competetive and
non competitive antgonists bind, if any.
Thank very much for your next help.
