Revolving around constriction by ESCRT-III

The endosomal sorting complex required for transport (ESCRT)-III is critical for membrane abscission; however, the mechanism underlying ESCRT-III-mediated membrane constriction remains elusive. A study of the dynamic assembly and disassembly of the ESCRT-III machinery in vitro and in vivo now suggests that the turnover of the observed spiralling filaments is critical for membrane abscission during cytokinesis
