Myosin I contributes to the generation of resting cortical tension.

Biophysical journal - 1 Aug 1999

Dai J, Ting-Beall H P, Hochmuth R M, Sheetz M P, Titus M A

Abstract excerpt

The amoeboid myosin I's are required for cellular cortical functions such as pseudopod formation and macropinocytosis, as demonstrated by the finding that Dictyostelium cells overexpressing or lacking one or more of these actin-based motors are defective in these processes. Defects in these processes are concomitant with changes in the actin-filled cortex of various Dictyostelium myosin I mutants. Given that the...
