Predicted to enable cytoskeletal protein binding activity; integrin binding activity; and protein kinase binding activity. Predicted to be involved in actin cytoskeleton organization; neuromuscular junction development; and positive regulation of cell-matrix adhesion. Predicted to act upstream of or within adult somatic muscle development. Located in neuromuscular junction and sarcolemma. Part of dystrophin-associated glycoprotein complex. Is expressed in several structures, including alimentary system; central nervous system; digit mesenchyme; genitourinary system; and nasal epithelium. Orthologous to human UTRN (utrophin).
