dc.description.abstract | The molecular control of the distribution and motion of acetylcholine receptors in the plasma membrane of developing rat myotubes in primary cell culture was investigated by fluorescence techniques. Acetylcholine receptors were marked with tetramethylrhodamine-labeled [alpha]-bungarotoxin and lateral molecular motion in the membrane was measured by the fluorescence photobleaching recovery technique. Three types of experiments are discussed: (I) The effect of enzymatic cleavages, drugs, cross-linkers, and physiological alterations on the lateral motion of acetylcholine receptors and on the characteristic distribution of acetylcholine receptors into patch and diffuse areas. (II) Observation of the distribution and/or motion of fluorescence-labeled concanavalin A receptors, lipid probes, cell surface protein, and stained cholinesterase in acetylcholine receptor patch and diffuse areas. (III) The effect of a protein synthesis inhibitor and electrical stimulation on membrane incorporation of new acetylcholine receptors.Some of the main conclusions are: (a) acetylcholine receptor lateral motion is inhibited by concanavalin A plant lectin and by anti-[alpha]-bungarotoxin antibody, but marginally enhanced by treatment with a local anesthetic; (b) patches are stabilized by an immobile cellular structure consisting of molecules other than the acetylcholine receptors themselves; (c) this structure is highly selective for acetylcholine receptors and not for other cell membrane components; (d) acetylcholine receptor patch integrity and diffuse area motion are independent of direct metabolic energy requirements and are sensitive to electrical excitation of myotube; (e) lipid molecules can move laterally in both acetylcholine receptor patches and diffuse areas; and (f) acetylcholine receptor lateral motion in diffuse areas and immobility in patch areas are not altered by specific agents which are known to affect extrinsic cell surface proteins, or cytoplasmic microfilaments and microtubules. | en_US |
