Abstract
It is thought that the dense actin filament networks found in the cortex of many cell types1–4 might account for the gelled consistency of the cortex5 and the exclusion of other organelles from this region of the cytoplasm6–8. We now demonstrate that a new actin-binding protein from Dictyostelium that gels actin in vitro is concentrated in the cell cortex, suggesting that this protein, in association with actin, accounts for the gel-like properties of this region of the cell.
