Background

Leucine‑rich repeat G‑protein‑coupled receptor 5 (Lgr5), also called GPR49, is a 907 amino acid (aa), approximately 97 kDa (calculated), seven‑transmembrane glycoprotein receptor in the Lgr family of cell surface receptors. The subfamily of Lgrs comprising Lgr4, Lgr5, and Lgr6 are G‑protein‑independent mediators of the potentiating effect of R‑Spondins on Wnt signaling (2). Lgr5 binds and forms complexes with R‑Spondins, Frizzled Wnt receptors and LRP Wnt co‑receptors. The region of the mouse Lgr5 long extracellular domain used as an immunogen shares 90% and 95% amino acid sequence identity with human and rat Lgr5, respectively. Lgr5 is found on embryonic and adult epithelial stem cells (3). Lgr5⁺ stem cells can produce all epithelial cell types of the intestinal crypts (4). It is upregulated in stem cells that give rise to cancers such as intestinal, hepatocellular, pancreatic and ovarian carcinomas (5,6). This antibody has been referred to as "RD20" by Peng et al.(1).
