Buffer before Lyophilization Tris/PBS-based buffer, 6% Trehalose, pH 8.0
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Protein FAQs
Storage Condition Store at -20°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Data

Function Non-receptor serine/threonine protein kinase which is necessary for the maintenance of skeletal muscle structure and function. May play a role in myocyte differentiation and survival by regulating the integrity of the nuclear envelope and the expression of muscle-specific genes. May also phosphorylate PPP1R12A and inhibit the myosin phosphatase activity to regulate myosin phosphorylation. Also critical to the modulation of cardiac contractility and to the maintenance of proper cardiac conduction activity probably through the regulation of cellular calcium homeostasis. Phosphorylates PLN, a regulator of calcium pumps and may regulate sarcoplasmic reticulum calcium uptake in myocytes. May also phosphorylate FXYD1/PLM which is able to induce chloride currents. May also play a role in synaptic plasticity.

  3. The data of this study demonstrated that DMPK knockout mice present altered beta-agonist-induced responses and suggest that this is due, at least in part, to a reduced density of beta(1)-adrenergic receptors in cardiac plasma membranes. PMID: 22190319
  4. Cytosolic DMPK participates in remodeling of the actomyosin cytoskeleton in developing skeletal muscle cells. PMID: 21295081

  16. Data show that during cardiac myocyte maturation, DMPK migrates from perinuclear to cellular membrane localization. Manipulating DMPK levels in cultured cardiac and skeletal myocytes has revealed a key role for DMPK in myocyte differentiation. PMID: 18729234
  17. The cellular location of CUG RNA aggregates is an important variable that influences toxicity in myotonic dystrophy pathology. PMID: 19092997
