Binding of antigen to the B-cell antigen receptor (BCR) triggers signaling that ultimately leads to B-cell activation. After BCR engagement and activation at the plasma membrane, phosphorylates PLCG2 at several sites, igniting the downstream signaling pathway through calcium mobilization, followed by activation of the protein kinase C (PKC) family members. PLCG2 phosphorylation is performed in close cooperation with the adapter protein B-cell linker protein BLNK. BTK acts as a platform to bring together a diverse array of signaling proteins and is implicated in cytokine receptor signaling pathways. Plays an important role in the function of immune cells of innate as well as adaptive immunity, as a component of the Toll-like receptors (TLR) pathway. The TLR pathway acts as a primary surveillance system for the detection of pathogens and are crucial to the activation of host defense. Especially, is a critical molecule in regulating TLR9 activation in splenic B-cells. Within the TLR pathway, induces tyrosine phosphorylation of TIRAP which leads to TIRAP degradation. BTK plays also a critical role in transcription regulation. Induces the activity of NF-kappa-B, which is involved in regulating the expression of hundreds of genes. BTK is involved on the signaling pathway linking TLR8 and TLR9 to NF-kappa-B. Transiently phosphorylates transcription factor GTF2I on tyrosine residues in response to BCR. GTF2I then translocates to the nucleus to bind regulatory enhancer elements to modulate gene expression. ARID3A and NFAT are other transcriptional target of BTK. BTK is required for the formation of functional ARID3A DNA-binding complexes. There is however no evidence that BTK itself binds ly to DNA. BTK has a dual role in the regulation of apoptosis. .\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCellular localization (datasheet):\u003c\/strong\u003e Cytoplasm. Cell membrane; Peripheral membrane protein. Nucleus. In steady state, BTK is predominantly cytosolic. Following B-cell receptor (BCR) engagement by antigen, translocates to the plasma membrane through its PH domain. Plasma membrane localization is a critical step in the activation of BTK. A fraction of BTK also shuttles between the nucleus and the cytoplasm, and nuclear export is mediated by the nuclear export receptor CRM1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTissue details (datasheet):\u003c\/strong\u003e Predominantly expressed in B-lymphocytes.\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCommonly studied in contexts related to Immunology,Innate Immunity,Protein Phosphorylation,Signal Transduction,TLR Signaling,Tyrosine Kinases.\u003c\/li\u003e\n\u003cli\u003eSupports comparative expression analysis across conditions, genotypes, or treatments when paired with appropriate controls.\u003c\/li\u003e\n\u003cli\u003eUseful for confirming target presence and subcellular distribution using orthogonal readouts (e.g., microscopy vs. immunoblotting).\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blot (WB):\u003c\/strong\u003e Compare relative target abundance and apparent size\/isoforms across samples; interpret bands in light of expected MW and potential PTMs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence \/ ICC:\u003c\/strong\u003e Visualize subcellular localization and co-localization patterns; consider fixation\/permeabilization compatibility and controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConsider isoforms, post-translational modifications, and processing that can shift apparent molecular weight or localization.\u003c\/li\u003e\n\u003cli\u003eUse appropriate positive and negative controls (e.g., KO\/KD, blocking peptide, or isotype controls) to support specificity interpretation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAs a monoclonal antibody, this reagent is expected to recognize a defined epitope, which can support consistency across lots when epitope accessibility is preserved.\u003c\/p\u003e\u003c!-- Sources (internal):\u003cbr\u003e- Product datasheet fields provided in this catalog row (vendor-supplied).\u003cbr\u003e- UniProt Knowledgebase (general protein annotations): https:\/\/www.uniprot.org\/\u003cbr\u003e- NCBI Gene (general gene-level references): https:\/\/www.ncbi.nlm.nih.gov\/gene\/\u003cbr\u003e--\u003e","brand":"Boster Bio","offers":[{"title":"100 uL\/vial \/ Unconjugated","offer_id":53069815054701,"sku":"P00245","price":370.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/p00245-wb.jpg?v=1772558649","url":"https:\/\/www.ebiohippo.com\/products\/anti-phospho-btk-y551-rabbit-monoclonal-antibody-bha21007566","provider":"BioHippo","version":"1.0","type":"link"}
