title: Translation of tubulin messenger ribonucleic acid.
abstract: Tubulin messenger RNA has been partially purified from embryonic chick brain. This messenger has been shown to be polyadenylated and capable of directing tubulin synthesis in an heterologous cell-free protein synthesizing system. Phosphocellulose fractions of IF-3 derived from embryonic leg muscle or brain were tested for their effect on tubulin and myosin synthesis in vitro. Phosphocellulose fraction four from either tissue source stimulates tubulin synthesis three fold. Myosin synthesis is enhanced significantly only by the muscle subfraction. This result suggests the existence of specific factors in muscle for the translation of the myosin messenger.
