LGR5 Rabbit Polyclonal Antibody

CAT#: TA336750

Rabbit Polyclonal Lgr5/GPR49 Antibody

Product Images

Immunocytochemistry/Immunofluorescence: Lgr5/GPR49 Antibody TA336750 - Hek293 cells were fixed in 4% paraformaldehyde for 10 minutes and permeabilized in 0.05% Triton X-100 in PBS for 5 minutes. The cells were incubated with anti-Lgr5/GPR49 Antibody TA336750 at 2 ug/ml overnight at 4C and detected with an anti-rabbit Dylight 488 (Green) at a 1:1000 dilution for 60 minutes. Nuclei were counterstained with DAPI (Blue). Cells were imaged using a 100X objective and digitally deconvolved.

• Background: 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.
