Biological background
LGR5 (protein: P2X purinoceptor 1) is a commonly studied target in molecular and cellular biology. Functional context (as provided): 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. . Reported cellular localization context: Cell membrane; Multi-pass membrane protein. Golgi apparatus, trans-Golgi network membrane; Multi-pass membrane protein. Rapidly and constitutively internalized to the trans-Golgi network at steady state. Internalization to the trans- Golgi network may be the result of phosphorylation at Ser-861 and Ser-864; however, the phosphorylation event has not been proven (PubMed:23439653). . Tissue expression notes (as provided): 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. .
Research relevance and current trends
- Research context keywords from the source record include: Cancer,G Protein Signaling,Signal Transduction,Signaling Pathway,Signaling Pathways,Stem Cells,Surface Molecules.
- Current studies often focus on connecting target abundance/localization to pathway perturbations across models, tissues, and cell states.
- Quantitative and multiplexed assays (e.g., imaging + immunoblot panels) are commonly used to compare phenotypes across conditions and time-courses.
Common research applications
- Western blotting (WB): assess relative target abundance across samples, treatments, or time-points.
- Flow cytometry: quantify target-positive populations and compare shifts in marker distributions.
- Immunoprecipitation (IP): enrich target complexes for downstream immunoblot or interaction analyses.
Workflow ideas (metafield): Validate LGR5 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect LGR5 expression by Western blot in cell or tissue lysates, Quantify LGR5-positive cells by flow cytometry in single-cell suspensions, Enrich LGR5 by immunoprecipitation from lysates for downstream analysis
Notes for experimental interpretation
- Consider isoforms and post-translational modifications (PTMs) that may shift apparent molecular weight or epitope accessibility.
- Apparent molecular weight may vary by sample type and processing (observed MW: 100-110 kDa; calculated MW: 99998 MW).
- Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
