The relatively flatter shape of F-actin as compared to G-actin allows myosin to preferentially bind F-actin over G-actin. This means that F-actin, not G-actin, is the functional form of actin. It composes a large part of the thin filaments in conjunction with mysoin to give muscle contractions<ref name="Holmes2"/><ref name="Holmes3>PMID:14508495</ref>. The structure of F-actin gives it large resistance to extensive forces, such as those experienced in muscle contraction<ref name="Mitchinson"/>. | The relatively flatter shape of F-actin as compared to G-actin allows myosin to preferentially bind F-actin over G-actin.
