GPCR dysfunction is implicated in quite a few diseases and therefore these proteins are of great interest to academia and the pharmaceutical industry. Leucine-rich repeat-containing GPCRs contain a characteristic extracellular domain that is certainly a vital modulator of intracellular signaling. One member of this class is the leucine-rich repeat-containing G-protein-coupled receptor 5 (LGR5), a stem cell marker in intestinal crypts, and mammary glands. LGR5 modulates Wnt signaling inside the presence on the ligand R-spondin (RSPO). The mechanism of activation of LGR5 by RSPO is not understood, nor will be the intracellular signaling mechanism identified. Not too long ago reported structures from the extracellular domain of LGR5 bound to RSPO reveal a horseshoe-shaped architecture produced up of consecutive leucine-rich repeats, with RSPO bound on the concave surface. This critique discusses the discovery of LGR5 along with the effect it can be obtaining on our understanding of stem cell and cancer biology on the colon. Moreover, it covers functional relationships recommended by sequence homology and structural analyses, as well as some intriguing conundrums with respect for the involvement of LGR5 in Wnt signaling.
