Recognizes and binds the forkhead DNA sequence motif (5'-GTAAACA-3') and can both act as a transcription activator or repressor, depending on the context. Together with FOXK2, acts as a key regulator of metabolic reprogramming towards aerobic glycolysis, a process in which glucose is converted to lactate in the presence of oxygen. Acts by promoting expression of enzymes for glycolysis (such as hexokinase-2 (HK2), phosphofructokinase, pyruvate kinase (PKLR) and lactate dehydrogenase), while suppressing further oxidation of pyruvate in the mitochondria by up-regulating pyruvate dehydrogenase kinases PDK1 and PDK4. Probably plays a role in gluconeogenesis during overnight fasting, when lactate from white adipose tissue and muscle is the main substrate. Involved in mTORC1-mediated metabolic reprogramming: in response to mTORC1 signaling, translocates into the nucleus and regulates the expression of genes associated with glycolysis and downstream anabolic pathways, such as HIF1A, thereby regulating glucose metabolism. Together with FOXK2, acts as a negative regulator of autophagy in skeletal muscle: in response to starvation, enters the nucleus, binds the promoters of autophagy genes and represses their expression, preventing proteolysis of skeletal muscle proteins. Acts as a transcriptional regulator of the myogenic progenitor cell population in skeletal muscle. Binds to the upstream enhancer region (CCAC box) of myoglobin (MB) gene, regulating the myogenic progenitor cell population. Promotes muscle progenitor cell proliferation by repressing the transcriptional activity of FOXO4, thereby inhibiting myogenic differentiation. Involved in remodeling processes of adult muscles that occur in response to physiological stimuli. Required to correct temporal orchestration of molecular and cellular events necessary for muscle repair. Represses myogenic differentiation by inhibiting MEFC activity. Positively regulates Wnt\/beta-catenin signaling by translocating DVL into the nucleus. Reduces virus replication, probably by binding the interferon stimulated response element (ISRE) to promote antiviral gene expression.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eExpression and localization notes:\u003c\/strong\u003e cellular localization: Nucleus., tissue context: Expressed in kidney..\u003c\/p\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blotting (WB):\u003c\/strong\u003e Compare FOXK1 levels across samples and conditions using appropriate loading and biological controls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry (IHC):\u003c\/strong\u003e Evaluate spatial distribution of FOXK1 in tissue sections, considering fixation and antigen retrieval effects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence \/ ICC:\u003c\/strong\u003e Assess subcellular localization patterns and co-localization with compartment markers in cultured cells.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e Quantify FOXK1-positive populations in single-cell suspensions with appropriate gating and controls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eELISA:\u003c\/strong\u003e Use antibody-based detection formats to assess antigen presence or binding in plate-based assays.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eAccount for isoforms, post-translational modifications, and sample-specific processing that can shift apparent molecular weight or epitope accessibility.\u003c\/li\u003e \u003cli\u003eUse positive\/negative biological controls where possible (e.g., known-expressing cells\/tissues, knockdown\/knockout models) and include appropriate secondary-only\/isotype controls for imaging workflows.\u003c\/li\u003e \u003c\/ul\u003e\u003ch2\u003eAdditional product notes (from provided fields)\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecificity:\u003c\/strong\u003e No cross reactivity with other proteins.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBackground:\u003c\/strong\u003e Forkhead box protein K1 is a transcription factor of the forkhead box family that in humans is encoded by the FOXK1 gene. It is mapped to 7p22.1. FOXK1 is one of the transcription factors managing the passage from the normal cellular respiration (complete glucose oxidation) to generating ATP and intermediaries for many other biochemical pathways. FOXK1 and its closely relate sibling FOXK2 induce aerobic glycolysis by upregulating the enzymatic machinery required for this (for example, hexokinase-2, phosphofructokinase, pyruvate kinase, and lactate dehydrogenase), while at the same time suppressing further oxidation of pyruvate in the mitochondria by increasing the activity of pyruvate dehydrogenase kinases 1 and 4.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross reactivity:\u003c\/strong\u003e No cross-reactivity with other proteins.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCellular localization:\u003c\/strong\u003e Nucleus.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTissue details:\u003c\/strong\u003e Expressed in kidney.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResearch category:\u003c\/strong\u003e Cell Biology\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProt entry for P85037: https:\/\/www.uniprot.org\/uniprot\/P85037 - NCBI Gene (ID 221937): https:\/\/www.ncbi.nlm.nih.gov\/gene\/221937 - Ensembl search (FOXK1): https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=FOXK1 - Human Protein Atlas search (FOXK1): https:\/\/www.proteinatlas.org\/search\/FOXK1 - PubMed search (FOXK1): https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=FOXK1 --\u003e","brand":"Boster Bio","offers":[{"title":"100 ug\/vial \/ Unconjugated","offer_id":53067716034925,"sku":"A07015-2","price":370.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Biotin","offer_id":53067928797549,"sku":"A07015-2-Biotin","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Cy3","offer_id":53067928830317,"sku":"A07015-2-Cy3","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro488","offer_id":53067928863085,"sku":"A07015-2-Fluoro488","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro550","offer_id":53067928895853,"sku":"A07015-2-Fluoro550","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro594","offer_id":53067928928621,"sku":"A07015-2-Fluoro594","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ FITC","offer_id":53067928961389,"sku":"A07015-2-FITC","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ HRP","offer_id":53067928994157,"sku":"A07015-2-HRP","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ APC","offer_id":53067929026925,"sku":"A07015-2-APC","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ PE","offer_id":53067929059693,"sku":"A07015-2-PE","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro647","offer_id":53067929092461,"sku":"A07015-2-Fluoro647","price":670.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Carrier Free","offer_id":53067929125229,"sku":"A07015-2-carrier-free","price":370.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/a07015-2-foxk1-primary-antibodies-wb-testing-1_1.jpg?v=1772609661","url":"https:\/\/www.ebiohippo.com\/products\/anti-foxk1-mnf-picoband-antibody-bha21002537","provider":"BioHippo","version":"1.0","type":"link"}
