Abstract
A partially purified fraction of poly(a)-rich brain mRNA coding for tubulin and actin was obtained by stepwise elution from an oligo(deoxythymidylate)-cellulose column and was efficiently translated in a wheat-germ cell-free system. The newly synthesized tubulin and actin migrated along with the authentic proteins on sodium dodecyl sulfate polyacrylamide gels and on sodium dodecyl sulfate-urea polyacrylamide gels, where tubulin alpha- and beta-subunits are separated. The two proteins synthesized in vitro were found to be biologically active; they could be induced to polymerize and were both precipitated by vinblastine. In addition, specific binding of tubulin to an affinity column of colchicine-Sepharose and actin to myosin were demonstrated.
