Peripheral ruffles

WebMar 22, 2013 · Membrane ruffles are highly dynamic and F-actin-rich structures and are classified into two types: peripheral ruffles and dorsal ruffles, according to their morphology and localization ( 1 ). Peripheral ruffles are formed by the bending upward of the leading edge and are associated with cell motility ( 2 ). WebFrom studies of ectopic expression, Miki et al. (2000) found that IRSP53 is essential for RAC to induce membrane ruffling, probably because it recruits WAVE2, which stimulates actin polymerization mediated by the ARP2/3 complex.
