Overview

Ankyrins are a family of proteins that mediates the attachment of integral membrane proteins to the cytoskeleton.^[1]

Ankyrin 1, was first discovered in the erythrocytes but also later found to be expressed in the brain and muscles. In erythrocytes, Ankyrin 1 links membrane receptor CD44 to inositol triphosphate and the cytoskeleton.^[2]

Ankyrin contains three functional domains: a conserved N-terminal ankyrin 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.

Ankyrin was discovered by Dr. G. Vann Bennett (M.D., PhD.) in 1976.
