Description
The protein encoded by this gene is a leucine-rich repeat-containing receptor (LGR) and member of the G protein-coupled, 7-transmembrane receptor (GPCR) superfamily. The encoded protein is a receptor for R-spondins and is involved in the canonical Wnt signaling pathway. This protein plays a role in the formation and maintenance of adult intestinal stem cells during postembryonic development. Several transcript variants encoding different isoforms have been found for this gene.
Bio-activity
Measured by its binding ability in a functional ELISA. When Recombinant Human R-Spondin 3 is coated at 0.5 μg/mL, Recombinant Human Lgr5/GPR49 Fc Chimera binds with an apparent Kd <0.1 nM. Measured by its ability to inhibit Topflash reporter activity in HEK293T human embryonic kidney cells. The ED50 for this effect is 1.5-7.5 μg/mL in the presence of 20 ng/mL Recombinant Human R-Spondin 2 and 5 ng/mL Recombinant Mouse Wnt-3a.
