Trim21 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 Mus musculus (Mouse) 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\u003eDissecting domain-specific functions of regulatory proteins involved in chromatin organization and transcriptional control.\u003c\/li\u003e \u003cli\u003eMapping protein–protein and protein–nucleic acid interactions that coordinate gene expression programs.\u003c\/li\u003e \u003cli\u003eBuilding in vitro assays for enzymatic activities and reader–writer–eraser mechanisms linked to epigenetic regulation.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRelevance:\u003c\/strong\u003e E3 ubiquitin-protein ligase whose activity is dependent on E2 enzymes, UBE2D1, UBE2D2, UBE2E1 and UBE2E2. Forms a ubiquitin ligase complex in cooperation with the E2 UBE2D2 that is used not only for the ubiquitination of USP4 and IKBKB but also for its self-ubiquitination. Component of cullin-RING-based SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complexes such as SCF(SKP2)-like complexes. A TRIM21-containing SCF(SKP2)-like complex is shown to mediate ubiquitination of CDKN1B ('Thr-187' phosphorylated-form), thereby promoting its degradation by the proteasome. Monoubiquitinates IKBKB that will negatively regulates Tax-induced NF-kappa-B signaling. Negatively regulates IFN-beta production post-pathogen recognition by polyubiquitin-mediated degradation of IRF3. Mediates the ubiquitin-mediated proteasomal degradation of IgG1 heavy chain, which is linked to the VCP-mediated ER-associated degradation (ERAD) pathway. Promotes IRF8 ubiquitination, which enhanced the ability of IRF8 to stimulate cytokine genes transcription in macrophages. Plays a role in the regulation of the cell cycle progression. Enhances the decapping activity of DCP2. Exists as a ribonucleoprotein particle present in all mammalian cells studied and composed of a single polypeptide and one of four small RNA molecules. At least two isoforms are present in nucleated and red blood cells, and tissue specific differences in RO\/SSA proteins have been identified. The common feature of these proteins is their ability to bind HY RNAs.2. Involved in the regulation of innate immunity and the inflammatory response in response to IFNG\/IFN-gamma. Organizes autophagic machinery by serving as a platform for the assembly of ULK1, Beclin 1\/BECN1 and ATG8 family members and recognizes specific autophagy targets, thus coordinating target recognition with assembly of the autophagic apparatus and initiation of autophagy. Acts as an autophagy receptor for the degradation of IRF3, hence attenuating type I interferon (IFN)-dependent immune responses . Represses the innate antiviral response by facilitating the formation of the NMI-IFI35 complex through 'Lys-63'-linked ubiquitination of NMI .\u003c\/p\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eEnzyme activity assays and kinetics measurements with defined substrates\/cofactors.\u003c\/li\u003e \u003cli\u003eInhibitor, activator, or substrate screening in biochemical assay formats.\u003c\/li\u003e \u003cli\u003eStructure–function analysis to interpret how sequence changes impact catalytic performance.\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 \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProtKB entry for Q62191 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/Q62191\/entry - NCBI Gene search (Trim21) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=Trim21 - PubMed search (Trim21) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=Trim21 - RCSB PDB search (Trim21) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=Trim21 - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065330295149,"sku":"CSB-BP733816MO-1MG","price":3278.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065513075053,"sku":"CSB-BP733816MO-100UG","price":1478.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065513107821,"sku":"CSB-BP733816MO-20UG","price":528.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-BP733816MO-SDS.jpg?v=1772476639","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-mouse-e3-ubiquitin-protein-ligase-trim21-trim21-bhp10510776","provider":"BioHippo","version":"1.0","type":"link"}
