EHD3 (EH-Domain Containing 3): EHD3 is a member of the EHD protein family involved in endocytic recycling. It plays a key role in the trafficking and recycling of membrane proteins back to the plasma membrane, maintaining proper cell surface composition and signaling. EHD3’s function in membrane trafficking is essential for cardiovascular health, and its dysregulation has been linked to heart diseases, emphasizing its importance in cardiac muscle cell function.
