fimbrin

fimbrin
An actin-binding protein that cross-links adjacent filaments tightly to form parallel actin fibers in vertebrate cells. It assists in maintaining cell polarity and development. [L. fimbriae, threads, fibers, + -in]

fim·brin (fimґbrin) a 68-kD actin-binding protein that cross-links actin filaments to form tight, regular bundles in the epithelial brush border microvilli and the stereocilia of hair cells. Called also plastin.
