摘要
Actin works within eukaryotic cells to facilitate a variety of cellular processes, which are driven by the assembly of G-actin (monomeric form) into F-actin (fibrous form), and the disassembly of F-actin into G-actin. F-actin adopts multiple conformations, which are specified by interactions with various actin-binding proteins. Knowledge of the multiple conformations of actin is the key for understanding its cellular functions. Recently, we published a refined model for F-actin. In this review, based on this model, we discuss the origin, mechanism, and possible physiological significance of the multiple conformations of F-actin.
