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. However, in Chara corallina, the organization of actin …
Actin's primary role in the cell is to form linear polymers called microfilaments that serve various functions in the cell's structure, trafficking networks, migration, and replication. The multifaceted role of actin relies on a few of the microfilaments' properties: First, the formation of actin filaments is reversible, and their function often involves undergoing rapid polymerization and depoly… WebIn most animal cells, a network of actin filaments is found in the region of cytoplasm at the very edge of the cell.
