GPCR dysfunction is implicated in quite a few ailments and hence these proteins are of wonderful interest to academia as well as the pharmaceutical industry. Leucine-rich repeat-containing GPCRs include a characteristic extracellular domain that is an important modulator of intracellular signaling. A single member of this class will be the leucine-rich repeat-containing G-protein-coupled receptor five (LGR5), a stem cell marker in intestinal crypts, and mammary glands. LGR5 modulates Wnt signaling in the presence in the ligand R-spondin (RSPO). The mechanism of activation of LGR5 by RSPO will not be understood, nor may be the intracellular signaling mechanism recognized. Lately reported structures of your extracellular domain of LGR5 bound to RSPO reveal a horseshoe-shaped architecture created up of consecutive leucine-rich repeats, with RSPO bound on the concave surface. This overview discusses the discovery of LGR5 and the effect it is actually having on our understanding of stem cell and cancer biology in the colon. Moreover, it covers functional relationships suggested by sequence homology and structural analyses, at the same time as some intriguing conundrums with respect to the involvement of LGR5 in Wnt signaling.
