| Research Abstract |
To approach the function of tubulin polyglutamylation in cilia/flagella motility, we examined the motile properties of a Chlamydomonas tpg1, a mutant that lacks a tubulin polygultamylating enzyme (TTLL9). Motility analyses in double mutants between tpg1 and various kinds of dynein-deficient mutants revealed that long-chain tubulin polyglutamylation affects the function of only one particular species of dynein, inner arm dynein e, among more than 10 species of axonemal dyneins. Furthermore, studies using another mutant, tpg2, showed that a protein designated FAP234 functions in the transport and stabilization of TTLL9.
