SOCS1 is involved in negative regulation of cytokines that signal through the JAK\/STAT3 pathway. Through binding to JAKs, inhibits their kinase activity. In vitro, also suppresses Tec protein-tyrosine activity. Appears to be a major regulator of signaling by interleukin 6 (IL6) and leukemia inhibitory factor (LIF). Regulates interferon-gamma mediated sensory neuron survival. Probable substrate recognition component of an ECS (Elongin BC-CUL2\/5-SOCS-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Seems to recognize JAK2. SOCS1 appears to be a negative regulator in IGF1R signaling pathway\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReagent standardization: using recombinant proteins as reference materials for quantitative calibration and cross-study comparability.\u003c\/li\u003e\n\u003cli\u003eInteraction-focused studies: mapping binding partners, affinity changes, and structure–function relationships across variants or domains.\u003c\/li\u003e\n\u003cli\u003eMulti-omic readouts: combining recombinant perturbations with transcript, protein, and functional endpoints to connect mechanism to phenotype.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAssay development and validation: use as a defined input or standard where protein identity is required.\u003c\/li\u003e\n\u003cli\u003eBinding studies: evaluate interaction strength and specificity using plate-based or biophysical formats.\u003c\/li\u003e\n\u003cli\u003eCell-response profiling: add protein to cultured cells and interpret downstream marker changes with appropriate controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpretation is most robust when signal changes are evaluated relative to matched controls (buffer-only, unrelated protein controls, or pathway controls) and when readouts are compared across dose and time.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIsoforms and PTMs can influence binding and activity; ensure the expressed region and expression system match your experimental needs.\u003c\/li\u003e\n\u003cli\u003eSpecies differences may affect receptor binding or antibody recognition; confirm species\/source alignment with your model.\u003c\/li\u003e\n\u003cli\u003eUse concept-level controls such as negative controls (no protein), matrix controls, or orthogonal readouts to support conclusions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProt keyword search: https:\/\/www.uniprot.org\/uniprotkb?query=Socs1 - NCBI Gene search: https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=Socs1 - PubMed search: https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=Socs1 - Ensembl search: https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=Socs1 - Reactome Pathway Browser: https:\/\/reactome.org\/content\/query?q=Socs1 --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53053082337645,"sku":"CSB-EP022388MO-1MG","price":2466.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53053266002285,"sku":"CSB-EP022388MO-100UG","price":578.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53053266035053,"sku":"CSB-EP022388MO-20UG","price":306.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP022388MO-SDS.jpg?v=1772173026","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-mouse-suppressor-of-cytokine-signaling-1-socs1-bhp10505256","provider":"BioHippo","version":"1.0","type":"link"}
