CRBN 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\u003eLinking protein expression or modification states to neuronal activity, synaptic plasticity, and circuit phenotypes.\u003c\/li\u003e \u003cli\u003eStudying receptor\/ligand or scaffolding interactions that influence synapse organization and signaling.\u003c\/li\u003e \u003cli\u003eDeveloping quantitative assays to track neurodegeneration- or injury-associated molecular changes.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRelevance:\u003c\/strong\u003e Substrate recognition component of a DCX (DDB1-CUL4-X-box) E3 protein ligase complex that mediates the ubiquitination and subsequent proteasomal degradation of target proteins, such as MEIS2 or ILF2 . Normal degradation of key regulatory proteins is required for normal limb outgrowth and expression of the fibroblast growth factor FGF8 . Maintains presynaptic glutamate release and consequently cognitive functions, such as memory and learning, by negatively regulating large-conductance calcium-activated potassium (BK) channels in excitatory neurons . Likely to function by regulating the assembly and neuronal surface expression of BK channels via its interaction with KCNT1 . May also be involved in regulating anxiety-like behaviors via a BK channel-independent mechanism .\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 \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProtKB entry for Q96SW2 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/Q96SW2\/entry - NCBI Gene search (CRBN) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=CRBN - PubMed search (CRBN) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=CRBN - RCSB PDB search (CRBN) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=CRBN - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065330688365,"sku":"CSB-BP842761HUc7-1MG","price":2980.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065513861485,"sku":"CSB-BP842761HUc7-100UG","price":1322.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065513894253,"sku":"CSB-BP842761HUc7-20UG","price":472.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-BP842761HUc7-SDS.jpg?v=1772476641","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-protein-cereblon-crbn-bhp10510786","provider":"BioHippo","version":"1.0","type":"link"}
