Ankyrin 1, also known as ANK1, is a protein that plays a crucial role in maintaining the structural integrity and proper functioning of cells. It is a member of the ankyrin family of proteins, which are known for their role in linking integral membrane proteins to the underlying cytoskeleton. ANK1 is particularly well-studied in the context of red blood cells, where it helps to anchor the cytoskeletal protein spectrin to the plasma membrane.
