WebActin is a globular protein that polymerizes (joins together many small molecules) to form long filaments. Because each actin subunit faces in the same direction, the actin filament is polar, with different ends, termed “barbed” and “pointed.” An abundant protein in nearly all eukaryotic cells, actin has been extensively studied in muscle cells. In muscle cells, the … WebTumor diagnosis by intermediate filament typing: a novel tool for surgical pathology Authors M Osborn , K Weber Abstract In most cell types intermediate or 10-mm filaments (IF) are a major cytoskeletal organization and, thus, directly or indirectly influence the structural appearance of the cytoplasm. irs 1120s fillable form
