Low density lipoprotein receptor-related protein 4 (LRP4) is expressed on the surface of the postsynaptic membranes. It acts as a receptor for agrin. The protein belongs to the low-density lipoprotein receptor-related proteins (LRPs) family. The LRP4 gene is localized on human chromosome 11p11.2.
Immunogen
Peptide with sequence CSNPSYRTSTQEVK , from the internal region of the protein sequence according to NP_002325.2.
Biochem/physiol Actions
LRP4 (Low density lipoprotein receptor-related protein 4) is a multifunctional protein which controls the extracellular cell signaling pathways including Wnt β-catenin signaling. It is highly essential for maintaining the bone mineral density. LRP4 binds to Dkk1 (dickkopf 1) and sclerostin to control the bone growth via Wnt and bone morphogenic protein (BMP) signaling pathways. Clinically, it is highly important for the development of osteoporosis. Mutation in the LRP4 gene causes an autosomal-recessive congenital disorder, Cenani-Lenz syndrome characterized with limb and kidney malformations.
