WebMay 28, 2002 · Actin is a highly conserved protein found in all eukaryotic organisms. Most organisms have multiple cytoplasmic actin genes that encode isoforms with slightly different amino acid sequences. These different isoforms are coexpressed in many cell types. Why organisms have multiple very similar cytoplasmic actin genes is unclear. WebCytoplasmic streaming occurs due to the motion of organelles attached to actin filaments via myosin motor proteins.
