Summary: 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).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
