Cytoskeletal linker protein. May promote and stabilize the formation of the actin and microtubule network. Interacts (via CH domain) with F-actin (PubMed:21561867). Interacts (via C terminus) with microtubules (PubMed:21561867). Interacts with MAPRE1 (PubMed:24706950). Localizes to microtubule and actin cytoskeletons. Expressed in the pancreas, heart, liver, placenta, brain, skeletal muscle, kidney and lung. The GAR domain modulates the binding strength to each cytoskeletal network. Belongs to the GAS2 family.
