WebIn vertebrates 3 main groups of actin isoforms (alpha, beta and gamma) have been identified. The alpha actins are found in muscle tissues and are a major constituent of the contractile apparatus. The beta and gamma actins coexist in most cell types as components of the cytoskeleton and as mediators of internal cell motility. WebMotility MreB has also been shown to be important in motility in some species. In Myxococcus xanthus, MreB and AglZ are important for forming a cytoskeleton onto which the gliding motility apparatus assembles. AglZ (another IF-like protein) assembles at the leading pole, migrates down the cell, and disassembles at the opposite pole.
