FHOD3 (Formin Homology 2 Domain Containing 3): FHOD3 is a protein belonging to the formin family, which plays a key role in organizing and regulating the actin cytoskeleton. It is especially important in cardiac muscle and other tissues, where it supports the assembly of actin filaments that affect cell shape, adhesion, and movement. FHOD3 is vital for processes like cell division, migration, and muscle contraction, contributing to cardiovascular and skeletal system function. Its regulatory role involves dynamic remodeling of the actin cytoskeleton, essential for heart development and performance.
