__TOC__
== Function ==


[[Agrin]] (Agr) is involved in the embryogenesis of the neuromuscular junction.  It is involved in the aggregation of acetylcholine receptors. Its N-terminal domain NtA binds laminin. The C-terminal of Agr has 3 laminin binding domains (LMB): G1-G3. The images at the left and at the right correspond to one representative Agrin, ''i.e.'' the crystal structure of chicken Agrin ([[3i70]]).
