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. [provided by RefSeq, Sep 2015]

Function:
Receptor for R-spondins that potentiates the canonical Wnt signaling pathway and acts as a stem cell marker of the intestinal epithelium and the hair follicle. Upon binding to R-spondins (RSPO1, RSPO2, RSPO3 or RSPO4), associates with phosphorylated LRP6 and frizzled receptors that are activated by extracellular Wnt receptors, triggering the canonical Wnt signaling pathway to increase expression of target genes. In contrast to classical G-protein coupled receptors, does not activate heterotrimeric G-proteins to transduce the signal. Involved in the development and/or maintenance of the adult intestinal stem cells during postembryonic development.

Subunit:
Identified in a complex composed of RNF43, LGR5 and RSPO1.

Subcellular Location:
Cell membrane; Multi-pass membrane protein

Tissue Specificity:
Expressed in skeletal muscle, placenta, spinal cord, and various region of brain. Expressed at the base of crypts in colonic and small mucosa stem cells. In premalignant cancer expression is not restricted to the cript base. Overexpressed in cancers of the ovary, colon and liver.

Similarity:
Belongs to the G-protein coupled receptor 1 family.
Contains 16 LRR (leucine-rich) repeats.
Contains 1 LRRNT domain.

Lgr5基因（Wnt细胞信号系统）是一种G蛋白偶联受体，已经被确定为几种成年组织和癌症中干细胞的一个独特标记。Lgr5最初是在结肠癌细胞中发现的，有报道称：在恶化前的小鼠腺瘤中也有发现，这说明Lgr5很可能也是其他组织成体干细胞和癌症干细胞的标志物。 Picture
