Actin-binding proteins (also known as ABP) are proteins that bind to actin. This may mean ability to bind actin monomers, or polymers, or both.
Many actin-binding proteins, including α-actinin, β-spectrin, dystrophin, utrophin and fimbrin, do this through the actin-binding calponin homology domain.
This is a list of actin-binding proteins in alphabetical order.
