GPR49/LGR5 (G protein-coupled receptor 49 / leucine-rich repeat-containing G protein-coupled receptor 5), also called FEX, GPR67, GRP49, HG38 or MGC117008), is structurally related to members of glycoprotein hormone receptor family including FSH-R, TSH-R and LH-R. LGRs (leucine-rich repeat-containing G-protein coupled receptor) are divided into three major subgroups: glycoprotein hormone receptors; the subgroup of GPR48, GPR49, and LGR6; and receptors of relaxin family ligands (LGR7 and LGR8), of which GPR49 is emerging as a significant player in stem cells biology as it is highly expressed on stem cells in small intestine, colon and hair follicle. Deficiency of GPR49 in mice has been shown to cause neonatal lethality characterized by ankyloglossia, gastrointestinal distension and induction of premature differentiation of Paneth cells. LGR5 is a downstream target gene of Wnt signaling pathway (critical for morphogenesis and tumorigenesis) and it has also been reported as a receptor for R-spondins which are potent mediators of Wnt/beta-catenin as well as Wnt/PCP signaling. Accordingly, when compared to normal tissues, LGR5 is found upregulated in certain cancers e.g liver cancer with beta-catenin mutations, basal cell carcinoma, colon and ovarian carcinomas.

FAQs for Lgr5/GPR49 Antibody (NBP1-28904). (Showing 1 - 3 of 3 FAQs).

  1. This morning I have a customer who has purchased NBP1-28904 and would like to test it in flow cytometry. She is new to flow and is wondering if you might have a recommended protocol. Also, I see that the immunogen is within aa 650-700 which appears to span both helical and cytoplasmic domains. Do you know if the exact immunogen is fully within one domain or the other? Is permeabilization required? Any information you have is much appreciated.
    • Unfortunately I cannot disclose anything more about the immunogen sequence; however, our lab does recommend permeabilization for using this antibody. This is our general flow cytometry protocol. Note that if she tests this antibody in flow, she would be eligible for our Innovators Reward Program.
  2. Is it possible to confirm that the actual immunogen is taken from within the actual cytoplasmic domain (aa 660-682)?
    • Yes, I can confirm that the immunogen falls within the cytoplasmic domain of this protein.
  3. Please inform us this item NBP1-28904 is stain cytoplasmic or stain Nuclus?
    • NBP1-28904 detects Lgr5/GPR49 protein which localize to Cell membrane and the Golgi apparatus. Therefore, this antibody should generate a staining pattern with more signal in membranes and in cytoplasm as patches around the nucleus of the cells. More information on this protein may be found at Uniprot site
