a leucine-rich repeat-containing G-protein-coupled receptor. Receptor for R-spondins, potent stimulators of adult stem cell proliferation. A marker of cycling, long-lived and multipotent adult stem cell populations. Target gene of Wnt signaling. A Wnt receptor component that enhances Wnt signaling by soluble R-spondin proteins. Intestinal Lgr5+ stem cells give rise throughout life to proliferation of cells in crypts, which migrate along the crypt-villus axis, differentiating into five main cell types. Wnt signaling plays a crucial role in the proliferation and differentiation of these crypt epithelial cells. Two isoforms of the human protein are produced by alternative splicing.
