Scientific Background: LRP4 (Low-density lipoprotein receptor-related protein 4) is a single-pass transmembrane receptor crucial for neuromuscular junction (NMJ) formation, bone development, and Wnt signaling regulation. It binds to neuronal agrin, activating the MuSK receptor (muscle-specific kinase), which triggers acetylcholine receptor (AChR) clustering and post-synaptic differentiation. Beyond the neuromuscular junction, LRP4 is essential for kidney development and limb development, particularly in branching morphogenesis. It binds and internalizes extracellular ligands for degradation by lysosomes. LRP4 serves as a receptor for [sclerostin] (SOST) and Dkk1, which are inhibitors of the Wnt signaling pathway, thereby regulating bone growth and remodeling. It is involved in the negative regulation of the canonical Wnt signalling pathway, being able to antagonize the LRP6-mediated activation of this pathway. It is a type I transmembrane protein with a large extracellular domain (containing LDL repeats, EGF-like repeats, and beta-propeller domains) and a short cytoplasmic tail. LRP4 mutations cause diseases like myasthenia gravis and congenital myasthenic syndrome. Autoantibodies targeting LRP4 are a known cause of seronegative myasthenia gravis, and genetic defects can lead to bone dysplasia.
