Detection of Lgr5/GPR49 in HEK293 Human Cell Line Transfected with Mouse Lgr5/GPR49 and eGFP by Flow Cytometry. HEK293 human embryonic kidney cell line transfected with (A) mouse Lgr5/GPR49 or (B) irrelevant transfectant and eGFP was stained with Rat Anti-Mouse Lgr5/GPR49 Monoclonal Antibody (Catalog # MAB82401) followed by Allophycocyanin-conjugated Anti-Rat IgG Secondary Antibody (Catalog # F0113). Quadrant markers were set based on control antibody staining (Catalog # MAB0061).

Background: Lgr5/GPR49

Leucine‑rich repeat G‑protein‑coupled Receptor 5 (Lgr5), also known as 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. 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. Lgr5+ stem cells can produce all epithelial cell types of the intestinal crypts. It is upregulated in stem cells that give rise to cancers such as intestinal, hepatocellular, pancreatic and ovarian carcinomas.
