Alpha-1-syntrophin (SNTA1)

Adapter protein that binds to and probably organizes the subcellular localization of an assortment of membrane proteins. May link various receptors to the actin cytoskeleton and the extracellular matrix through the dystrophin glycoprotein complex.

Plays an important role in synapse formation and in the organization of UTRN and acetylcholine receptors at the neuromuscular synapse. Binds to phosphatidylinositol 4,5- bisphosphate (By similarity).
