Function

MYS2_DICDI Myosin is a protein that binds to actin and has ATPase activity that is activated by actin.ACTNA_DICDI F-actin cross-linking protein which is thought to anchor actin to a variety of intracellular structures. This is a bundling protein. Increases the actin-stimulated ATPase activity of myosin. Involved in vegetative cell growth, phagocytosis, motility and development, probably through stabilization of the actin network in the cortical cytoskeleton.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8]
