Human Lgr5/GPR49 Alexa Fluor® 750-conjugated Antibody Summary

Species Reactivity

Human

Specificity

Detects human Lgr5/GPR49 in ELISA. Stains human and mouse Lgr5 transfected cells but not irrelevant transfectants in Flow Cytometry and Immunocytochemistry. This antibody, also known as "RD42", has been found to detect an epitope in C-terminal LRR cap of LGR5 (Ref. 1).

Background: Lgr5/GPR49

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 human Lgr5 long extracellular domain used as an immunogen shares 90% amino acid sequence identity with mouse 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). Abnormal LGR5 expression and regulation in stem cells might give rise to cancers such as intestinal, hepatocellular, pancreatic and ovarian carcinomas (5,6). This antibody has been referred to as "RD42" in Peng et al. (1).
