Autor: Alexander N. Vasiliev, Serguei N. Skatchkov, Misty J. Eaton, V. V. Kravtsova, Tatiana M. Drabkina, Igor I. Krivoi, Frederic Mandel

Publikováno v: Pflügers Archiv - European Journal of Physiology. 452:756-765

Previous studies have shown that nanomolar acetylcholine (ACh) produces a 2 to 4-mV hyperpolarization of skeletal muscle fibers putatively due to Na(+),K(+)-ATPase activation. The present study elucidates the involvement of the nicotinic ACh receptor

[From diversity of molecular forms to functional specialization of oligomeric proteins, nicotinic acetylcholine receptor, acetylcholinesterase and Na+, K+-ATPase]

Autor: T M, Drabkina, I I, Krivoĭ

Publikováno v: Tsitologiia. 46(2)

The review is devoted to the issue of diversity of molecular forms of oligomeric proteins using as examples members of the three protein classes: nicotinic acetylcholine receptor, acetylcholinesterase, and Na,K-ATPase. The data are presented on the m
