This product corresponds to the Mycobacterium tuberculosis (strain CDC 1551 \/ Oshkosh) sequence context, which can be important when comparing homologs or orthologs across model systems. For curated functional annotations, domains, and sequence features, consult primary databases (e.g., UniProt\/NCBI) and the recent literature for the specific organism and isoform.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eUsing recombinant proteins to enable quantitative binding measurements and reagent benchmarking.\u003c\/li\u003e \u003cli\u003eStudying domain- and isoform-specific effects in pathway models and interaction networks.\u003c\/li\u003e \u003cli\u003eDeveloping robust, reproducible assays that connect molecular readouts to cellular phenotypes.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRelevance:\u003c\/strong\u003e Probably helps membrane protein MT1454 (P55) transport triacylglycerides (TAG) across the inner cell membrane into the periplasm and probably ultimately to the outer membrane. TAG probably regulates lipid metabolism and growth regulation. Binds di- and triacylated phosphatidyl-myo-inositol mannosides (PIMs), and glycolipid lipoglycan modulins lipoarabinomannan (LAM) and lipomannan (LM), facilitating their recognition by TLR2. Required for activity of drug efflux transporter MT1454. Required, probably with MT1454, for normal surface localization of LAM. Constitutes a host TLR2 agonist (toll-like receptor).\u003c\/p\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eAssay and standard development for immunoassays or binding-based detection methods.\u003c\/li\u003e \u003cli\u003eProtein–protein interaction studies (e.g., receptor–ligand or complex assembly) using purified components.\u003c\/li\u003e \u003cli\u003eStructure–function analysis, including domain mapping or evaluation of sequence variants.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eIn quantitative assay development, changes in binding or activity readouts are typically interpreted relative to appropriate negative\/positive controls and, where possible, orthogonal assay formats that support the same conclusion.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eRecombinant constructs may represent a defined region (domain) rather than the full-length protein; interpret results in the context of the expressed region.\u003c\/li\u003e \u003cli\u003eTag or fusion elements can aid purification and detection but may influence binding surfaces or oligomerization; consider tag controls when relevant.\u003c\/li\u003e \u003cli\u003eSpecies and isoform differences can affect interaction partners and post-translational modifications; align experimental controls to the intended biological context.\u003c\/li\u003e \u003cli\u003eE. coli expression can limit eukaryotic post-translational modifications; for modification-dependent biology, interpret results accordingly.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProtKB entry for P9WK44 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/P9WK44\/entry - NCBI Gene search (lprG) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=lprG - PubMed search (lprG) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=lprG - RCSB PDB search (lprG) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=lprG - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065271673197,"sku":"CSB-EP358685MVZ-1MG","price":2466.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065390752109,"sku":"CSB-EP358685MVZ-100UG","price":729.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065390784877,"sku":"CSB-EP358685MVZ-20UG","price":388.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP358685MVZ-SDS.jpg?v=1772476403","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-mycobacterium-tuberculosis-lipoarabinomannan-carrier-protein-lprg-lprg-bhp10508922","provider":"BioHippo","version":"1.0","type":"link"}
