The protein is linear and so we form this linear type of structure and it's the thinnest type of structure. It's about six to 7 nm in length. Now, the function of our microfiling is in muscle contraction, in phagocytosis, in tensile strength and cytoplasmic streaming. So cytoplasmic streaming basically refers to the amoeboid like movement of our cell. Phagocytosis refers to our invagination and engulfing of extracellular materials using the cell membrane. And tensile strength basically means our cell is able to resist tensile forces and tensile pressures.
