ParM is an actin homologue that is coded in a plasmid and it is involved in the regulation of plasmid DNA. ParMs from different bacterial plasmids can form astonishingly diverse helical structures … See more Actin is a family of globular multi-functional proteins that form microfilaments in the cytoskeleton, and the thin filaments in muscle fibrils. It is found in essentially all eukaryotic cells, where it may be present at a concentration … See more Monomeric actin, or G-actin, has a globular structure consisting of two lobes separated by a deep cleft. The bottom of the cleft represents the “ATPase fold”, a structure conserved among ATP and GTP-binding proteins that binds to a magnesium ion and … See more Actin filaments are often rapidly assembled and disassembled, allowing them to generate force and support cell movement. … See more Actin and closely related proteins are present in all organisms, suggesting the common ancestor of all life on Earth had actin. Actin is one … See more 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, … See more Although most yeasts have only a single actin gene, higher eukaryotes, in general, express several isoforms of actin encoded by a family of … See more The majority of mammals possess six different actin genes.
