Agrin is a large proteoglycan whose best-characterised role is in the development of the neuromuscular junction during embryogenesis. Agrin is named based on its involvement in the aggregation of acetylcholine receptors during synaptogenesis. In humans this protein is encoded by the AGRN gene.This protein has nine domains homologous to protease inhibitors. It may also have functions in other tissues and during other stages of development.
