<unk>  are a family of proteins that mediates the attachment of integral membrane proteins to the cytoskeleton.<unk> 1, was first discovered in the erythrocytes but also later found to be expressed in the brain and muscles. In erythrocytes,<unk> 1 links membrane receptor CD44 to inositol triphosphate and the cytoskeleton.<unk> contains three functional domains: a conserved N-terminal<unk> repeat domain (ARD) consisting of 22–24 tandem repeats of 33 amino acids, a spectrin binding domain and a variably sized C-terminal regulatory domain.<unk> was discovered by Dr. G. Vann Bennett (M.D., PhD.) in 1976.
