Cellular Energetics: Actin and Myosin Abstain from ATP during Starvation

Energy is required for all cellular functions and diverse mechanisms allow the cell to overcome acute energy starvation. A new study reveals that starved cells inhibit type V myosins and actin depolymerization, measures that may conserve energy while temporarily retaining cell polarity. Energy is re...
