TFAM 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\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 Binds to the mitochondrial light strand promoter and functions in mitochondrial transcription regulation . Component of the mitochondrial transcription initiation complex, composed at least of TFB2M, TFAM and POLRMT that is required for basal transcription of mitochondrial DNA . In this complex, TFAM recruits POLRMT to a specific promoter whereas TFB2M induces structural changes in POLRMT to enable promoter opening and trapping of the DNA non-template strand . Required for accurate and efficient promoter recognition by the mitochondrial RNA polymerase . Promotes transcription initiation from the HSP1 and the light strand promoter by binding immediately upstream of transcriptional start sites . Is able to unwind DNA . Bends the mitochondrial light strand promoter DNA into a U-turn shape via its HMG boxes . Required for maintenance of normal levels of mitochondrial DNA . May play a role in organizing and compacting mitochondrial DNA .\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 Q00059 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/Q00059\/entry - NCBI Gene search (TFAM) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=TFAM - PubMed search (TFAM) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=TFAM - RCSB PDB search (TFAM) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=TFAM - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065323250029,"sku":"CSB-EP023413HU-1MG","price":2466.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065498132845,"sku":"CSB-EP023413HU-100UG","price":578.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065498165613,"sku":"CSB-EP023413HU-20UG","price":306.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP023413HU-SDS.jpg?v=1772476618","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-transcription-factor-a-mitochondrial-tfam-bhp10510564","provider":"BioHippo","version":"1.0","type":"link"}
