MAP1LC3B refers to a protein target that is studied across multiple biological contexts; annotations and nomenclature can vary by species and isoform. This product corresponds to the Homo sapiens (Human) 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\u003eMapping pathway dependencies and signaling networks that drive tumor growth and drug resistance.\u003c\/li\u003e \u003cli\u003eDeveloping and benchmarking biomarker assays (e.g., immunoassays or binding reagents) for candidate targets.\u003c\/li\u003e \u003cli\u003eCharacterizing protein variants, domains, or interaction partners relevant to targeted therapeutics and precision oncology.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRelevance:\u003c\/strong\u003e Ubiquitin-like modifier involved in formation of autophagosomal vacuoles (autophagosomes) . Plays a role in mitophagy which contributes to regulate mitochondrial quantity and quality by eliminating the mitochondria to a basal level to fulfill cellular energy requirements and preventing excess ROS production . In response to cellular stress and upon mitochondria fission, binds C-18 ceramides and anchors autophagolysosomes to outer mitochondrial membranes to eliminate damaged mitochondria . While LC3s are involved in elongation of the phagophore membrane, the GABARAP\/GATE-16 subfamily is essential for a later stage in autophagosome maturation . Promotes primary ciliogenesis by removing OFD1 from centriolar satellites via the autophagic pathway . Through its interaction with the reticulophagy receptor TEX264, participates in the remodeling of subdomains of the endoplasmic reticulum into autophagosomes upon nutrient stress, which then fuse with lysosomes for endoplasmic reticulum turnover . Upon nutrient stress, directly recruits cofactor JMY to the phagophore membrane surfaces and promotes JMY's actin nucleation activity and autophagosome biogenesis during autophagy .\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 Q9GZQ8 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/Q9GZQ8\/entry - NCBI Gene search (MAP1LC3B) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=MAP1LC3B - PubMed search (MAP1LC3B) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=MAP1LC3B - RCSB PDB search (MAP1LC3B) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=MAP1LC3B - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065323577709,"sku":"CSB-EP887936HU-1MG","price":2062.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065498460525,"sku":"CSB-EP887936HU-100UG","price":480.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065498493293,"sku":"CSB-EP887936HU-20UG","price":256.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP887936HU-SDS.jpg?v=1772476594","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-microtubule-associated-proteins-1a-1b-light-chain-3b-map1lc3b-bhp10510572","provider":"BioHippo","version":"1.0","type":"link"}
