Effects On Pharmacological Properties Of Chimeric Α6Β2Β3* Achrs With Α3 Cytoplasmic Domain(S) And The Ml (Methionine To Leucine) Mutation At Position 211 Of Α6, Carson K. Ley

α6β2β3* acetylcholine receptors (AChRs) on dopaminergic neurons located in the brain are critical targets for drugs to treat nicotine addiction and Parkinson's disease. a6 and a3 are acetylcholine receptor (AChR) subunits closely related in sequence. a3 assembles efficiently with b2 subunits to form functional AChRs in Xenopus laevis oocytes, but a6 does not, presumably because specific chaperones needed for efficient expression are missing (Gotti et al., 2010). Chimeras of a6 with a3 assemble efficiently to form functional AChRs . To be useful and not misleading, it is vital that the chimeras incorporate only enough a3 sequence to insure efficient assembly …
