Agrin is a heparan sulfate basal glycoprotein that is critical for the formation and maintenance of the neuromuscular junction (NMJ). It forms the AGRN-LRP4 receptor complex, activates MUSK and regulates gene transcription and AChR clusters in the postsynaptic membrane to form the NMJ. Agrin Protein, Human (1073a.a, CHO, His) is the recombinant human-derived Agrin protein, expressed by CHO , with C-6*His labeled tag.

Agrin is a heparan sulfate basal lamina glycoprotein crucial for the formation and maintenance of the neuromuscular junction (NMJ), orchestrating key events in postsynaptic differentiation. As a component of the AGRN-LRP4 receptor complex, it induces the phosphorylation and activation of MUSK, leading to NMJ formation by regulating processes such as gene transcription and AChR clustering in the postsynaptic membrane, where calcium ions play a pivotal role. The neuronal function of Agrin is intricately regulated by alternative splicing, glycan binding, and proteolytic processing. In neurons, it modulates calcium ion homeostasis, inducing an increase in cytoplasmic calcium ions. Agrin also acts differentially in the central nervous system (CNS) by inhibiting the alpha(3)-subtype of Na+/K+-ATPase, evoking depolarization at CNS synapses. The secreted isoform serves as a bridge between motor neurons and the basal lamina by binding laminin, while the transmembrane form, predominant in brain neurons, induces dendritic filopodia and synapse formation in mature hippocampal neurons through glycosaminoglycan chains and the action of Rho-family GTPases.
