pubmed:abstractText |
Cilia and flagella contain at least eight different types of dynein arms. It is not entirely clear how the different types of arms are organized along the axoneme. In addition, the role each different type of dynein plays in ciliary or flagellar motility is not known. To initiate studies of dynein organization and function in cilia, we have introduced a mutation into one dynein heavy chain gene (DYH6) in Tetrahymena themophila by targeted gene knockout. We have generated mutant cells that lack wild-type copies of the DYH6 gene. We have shown that the DYH6 gene encodes one heavy chain (HC2) of Tetrahymena 18S dynein and that 18S dynein occupies the I1 position in the ciliary axoneme. We have also shown that Tetrahymena I1 is required for normal motility, normal feeding and normal doubling rate.
