SYNOPSIS. Tetrahymena outer doublet tubulin was compared with neurotubulin and Chlamydomonas flagellar tubulin on SDS-polyacrylamide gels. Tetrahymenaα tubulin did not comigrate with either brain or flagellar α tubulins, although brain, flagellar, and ciliary β tubulins all comigrated. Axonemal tubulin from Tetrahymena strain ST was compared with this tubulin from strains W. S. HSM, and E, and all were found to have the same mobilities.Poly-A containing RNA was separated from whole cell Tetrahymena RNA by oligo-dT cellulose chromatography. Poly-A+ RNA from 24-h cultures (early exponential growth) stimulated greater incorporation of amino acids into polypeptides in the wheat germ cell-free translation system than did poly-A+ RNA from 36-h and 49-h cultures. When separated on SDS-polyacrylamide gels, the translation products of the 24-h poly-A + RNA had 2 prominent protein bands which comigrated with α and β tubulin isolated from Tetrahymena cilia. These bands were not found in the translation products of poly-A+ RNA isolated from 49-h cultures or in the translation products ofpoly-A- RNA.
