Beta-adducin (ADD2)

Membrane-cytoskeleton-associated protein that promotes the assembly of the spectrin-actin network. Binds to the erythrocyte membrane receptor SLC2A1/GLUT1 and may therefore provide a link between the spectrin cytoskeleton to the plasma membrane.

Binds to calmodulin. Calmodulin binds preferentially to the beta subunit.
