This enzyme belongs to the AGC kinase family and plays a central role in muscle structure and function. Myotonin-protein kinase regulates actomyosin organization, calcium homeostasis, and cell signaling in cardiac and skeletal muscle. The DMPK antibody enables detailed exploration of how this kinase influences muscle physiology, signal transduction, and disease mechanisms associated with myotonic dystrophy type 1 (DM1).\u003cbr\u003e\u003cbr\u003eMyotonin-protein kinase localizes to the sarcolemma, cytoplasm, and nuclear envelope of muscle cells, where it phosphorylates substrates involved in cytoskeletal organization and ion channel regulation. It contributes to the maintenance of sarcomere integrity and calcium signaling required for normal muscle contraction. The DMPK antibody is used to assess protein expression and localization, providing insights into how loss or mutation of this kinase disrupts muscular homeostasis.\u003cbr\u003e\u003cbr\u003eExpansion of CTG trinucleotide repeats in the 3? untranslated region of the DMPK gene causes DM1, a multisystem disorder characterized by muscle weakness, myotonia, and cardiac conduction defects. This repeat expansion leads to toxic RNA accumulation, altered splicing of multiple genes, and reduced DMPK protein levels. The DMPK antibody supports investigations into these molecular effects by allowing direct measurement of protein expression in affected tissues. Studies using this reagent have clarified that decreased Myotonin-protein kinase activity contributes to muscle atrophy and electrical instability in DM1 patients.\u003cbr\u003e\u003cbr\u003eBeyond myotonic dystrophy, DMPK signaling intersects with Rho GTPase and MAPK pathways, suggesting roles in cytoskeletal dynamics and stress responses. The DMPK antibody is a valuable reagent for studying these signaling networks and their involvement in cardiac hypertrophy, smooth muscle contractility, and cell migration. In cardiac research, immunohistochemical detection using the DMPK antibody reveals its presence in intercalated discs and perinuclear regions, correlating with its function in maintaining contractile coordination.\u003cbr\u003e\u003cbr\u003eExperimental applications for the DMPK antibody include western blotting, immunofluorescence, and immunohistochemistry. These assays permit detailed characterization of Myotonin-protein kinase in tissue and cellular models.\u003c\/div\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).\u003c\/li\u003e\n\u003cli\u003eConsidering isoforms and post-translational regulation when interpreting protein-level changes.\u003c\/li\u003e\n\u003cli\u003eComparing results across species and model systems with matched controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eWestern blotting:\u003c\/strong\u003e compare relative abundance and activation-state changes across conditions.\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eInterpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSignal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.\u003c\/li\u003e\n\u003cli\u003eSpecies differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAntibody notes:\u003c\/strong\u003e Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.\u003c\/p\u003e\u003c!-- Sources (internal): - UniProt search — UniProt — https:\/\/www.uniprot.org\/uniprotkb?query=DMPK - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=DMPK - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=DMPK - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/DMPK - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=DMPK+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"Adding 0.2 ml of distilled water will yield a concentration of 500 ug\/ml \/ 100 ug","offer_id":53047287873901,"sku":"FY12356","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_e079d3a5-bd65-4c84-8d2d-b965fe4a01b7.jpg?v=1782236996","url":"https:\/\/www.ebiohippo.com\/products\/dmpk-antibody-myotonin-protein-kinase-bha17135259","provider":"BioHippo","version":"1.0","type":"link"}
