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 endocytic hemoglobin import into cell; positive regulation of transport; and response to vitamin D. 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).
