Agrin CDNA Clones

Agrin is a 400-600 kDa heparan sulfate proteoglycan component of the extracellular matrix. Multiple forms of are generated by alternative splicing and proteolytic cleavage. Agrin binds to BMP-2, BMP-4, and TGF-beta, and it blocks BMP-induced signaling through BMPR-IA. Agrin binds to a complex of alpha-Dystroglycan, MuSK, and LRP4 on myotubes and induces the clustering of AChR and motoneuron-myotube adhesion at the neuromuscular junction. It binds the Abeta (1-40) peptide in Alzheimer’s ...
