Directionality of F-actin cables changes during the fission yeast cell cycle

Nat Cell Biol. 2005 Sep;7(9):916-7. doi: 10.1038/ncb1295.

Abstract

Longitudinal F-actin cables are thought to be important for transporting materials for polarized cell growth in fission yeast. We show that most F-actin in the cables is oriented such that the barbed end faces the nearest cell tip during interphase; however, this directionality is reversed during mitosis. These orientations of F-actin ensure proper transport of materials to growing sites during these cell-cycle stages.
