Abstract:
:Rapid axonal transport of proteins in retinal ganglion cells of the rabbit was studied following intraocular injections of labelled amino acids. Approximately 10% of the transported radioactivity was found in the supernatant following homogenization and high-speed centrifugation of the nerve terminal region. Relatively simple manipulations with ionic strength, pH and the presence of a chelating agent could solubilize an equivalent amount of radioactivity from the pellet. Lithium diiodosalicylate solubilized most rapidly transported membrane proteins. Gel filtration of readily soluble rapidly transported radioactivity gave a main macromolecular radioactive peak with an approximate mol. wt. of 500,000 dalton as determined on Sephadex G-200. However, gel filtration on Sepharose CL-6B gave a mol. wt. of about 160,000 for the same radioactive peak. SDS polyacrylamide gel electrophoresis of rapidly transported soluble proteins and fractions derived from these proteins via gel filtration and ion exchange chromatography revealed in all cases a very complex picture of labelled polypeptides. Thus rapid axonal transport of soluble proteins in this system seems to involve many different macromolecules.
