Actin and tubulin in Tetrahymena.
Tubulin and actin are cytoskeletal proteins known to play a major role in dividing cells. Tetrahymena pyriformis, a ciliated protozoan, was used as a model system for investigating tubulin synthesis during cilia regeneration and during the cell cycle. Until recently the identification of actin in Tetrahymena has been controversial. In this report evidence for the presence of actin in Tetrahymena is reviewed and control of actin gene expression during the cell cycle is discussed.
