Product Type Specific: DMPK protein kinase pan-specific antibody
Antibody Code: NK264-1
Antibody Target Type: Pan-specific
Protein UniProt: Q09013
Protein SigNET: DMPK1
Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Human DMPK1 (DMPK) sequence peptide Cat. No.: PE-01BCR70
Antibody Immunogen Sequence: CMALRDSEVPGPTPMELEA
Antibody Immunogen Description: Corresponds to amino acid residues C407 to A425; Just after kinase catalytic domain.
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: DMPK1 (Dystrophia myotonica protein kinase) is a protein-serine/threonine kinase of the AGC group and DMPK family, and found only in mammals. It is a protein kinase that is essential for maintaining skeletal muscle structure, regulating cardiac calcium homeostasis, and stabilizing the nuclear envelope. It acts as a signaling molecule, likely regulating myosin phosphatase, calcium pumps, and potentially ROS (reactive oxygen species) protection. It is activated in response to G protein second messengers. Phosphorylation by Raf1 may result in activation of DMPK. Substrates include phospholemman (PLN) and myosin phosphatase. It is composed of a kinase domain, a regulatory domain, and a coiled-coil domain that enhances its activity. It is maintained in an inactive conformation by the negative autoregulatory C-terminal coiled-coil region. It is often associated with the membrane, specifically at the nuclear envelope, sarcolemma, and neuromuscular junctions, through a C-terminal hydrophobic domain. Proteolytic processing of the C-terminus may remove the transmembrane domain and release the kinase from membranes stimulating its activity. The C-terminus of the protein may also be determined by alternative splicing, influencing its localization to the endoplasmic reticulum, mitochondria, or cytosol. Its dysfunction, caused by CTG triplet repeat expansions, results in myotonic dystrophy type 1 (DM1). While the mutation affects mRNA processing and creates toxic RNA that disrupts cell function, it may also lead to decreased or defective DMPK protein.
