Prokaryotes vs. Eukaryotes âDifferences. Eukaryotes as well as protists, a miscellany group made up of eukaryote-like plant, animal and fungi missing one or more characteristics to be defined as purely eukaryotic, differ greatly from prokaryotes in structure.
It is now clear that prokaryotic cells possess actin and that a dynamic actin-like cytoskeleton is involved in a variety of essential cellular processes in bacteria. These functions, like those of the eukaryotic actin cytoskeleton, require the targeting and accurate positioning of proteins and molecular complexes.he discovery of the prokaryotic homologues of actin (as well as of other cytoskeletal elements in bacteria) has forced a radical rethink about the origin of the cytoskeleton and revolutionized our view of bacterial cell architecture.
A small increase in SMA or actin antibody may be present in up to 50% of patients with primary biliary cirrhosis (PBC). The SMA autoantibody may also be found in other conditions, such as infectious mononucleosis, hepatitis C, and some cancers.n type 1, a high level (titer) of SMA or actin antibodies and/or ANA are present in the blood. In people with type 2, the titer of LKM1 is increased. Type 2 is uncommon in the United States.
