Role of fimbrin and villin in determining the interfilament distances of actin bundles

From X-ray diffraction patterns the interfilament distances of native and reconstituted actin bundles, and of purified actin gels subjected to a range of g forces by centrifugation, have been obtained and compared. The results suggest that bundling proteins, such as villin or fimbrin, cross-link actin filaments around a minimum distance probably set by… CONTINUE READING
