Lrp2 Gene Summary [Rat]
Enables several functions, including PDZ domain binding activity; insulin-like growth factor I binding activity; and low-density lipoprotein particle receptor binding activity. Involved in several processes, including chemoattraction of axon; positive regulation of transport; and protein transport. Located in several cellular components, including apical plasma membrane; axonal growth cone; and brush border membrane. Part of receptor complex. Used to study hypertension. Biomarker of autosomal dominant polycystic kidney disease; end stage renal disease; membranous glomerulonephritis; and nephrosis. Human ortholog(s) of this gene implicated in Donnai-Barrow syndrome and autoimmune thyroiditis. Orthologous to human LRP2 (LDL receptor related protein 2).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Lrp2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
