G and f actin
WebIt is widely known that F- and G-actin interact with a multitude of proteins in the cell (14). At present there are over 150 known actin binding proteins (ABPs), which accounts for approximately 25% of cellular protein. ABPs impart a great deal of functional diversity upon the actin cytoskeleton which is involved in processes such as muscle ...
