EHD3 (EH-Domain Containing 3): EHD3 is a member of the EHD protein family involved in endocytic recycling. It plays a vital role in the trafficking and recycling of membrane proteins back to the plasma membrane, maintaining the proper composition and signalling of the cell surface. The function of EHD3 in membrane trafficking is crucial for cardiovascular health, and its dysregulation has been associated with heart diseases, highlighting its importance in the function of cardiac muscle cells.
