Specification
Product Description
Human DMPK (AAA75236.1, 1 a.a. - 544 a.a.) partial recombinant protein with GST tag expressed in baculovirus infected Sf21 cells.
Host
insect
Theoretical MW (kDa)
88
Form
Liquid
Preparation Method
Baculovirus infected insect cell (Sf21) expression system
Purification
Glutathione sepharose chromatography
Purity
82 % by SDS-PAGE/CBB staining
Activity
The activity was determined by ELISA. The enzyme was incubated with GST-fused substrate protein, and after stopping kinase reaction by EDTA, the reaction solution was transferred into glutathione- coated plate. Phosphorylation was detected by anti-phospho antibody and HRP-labeled anti-rabbit IgG. Substrate: MYPT1. ATP: 100 uM.
Quality Control Testing
Loading 1 ug protein in SDS-PAGE
Storage Buffer
In 50 mM Tris-HCl, 150 mM NaCl, pH 7.5 (0.1% CHAPS, 1 mM DTT, 10% glycerol)
Storage Instruction
Store at -80°C.
Aliquot to avoid repeated freezing and thawing.Note

HyperlinkGene Summary
The protein encoded by this gene is a serine-threonine kinase that is closely related to other kinases that interact with members of the Rho family of small GTPases. Substrates for this enzyme include myogenin, the beta-subunit of the L-type calcium channels, and phospholemman. The 3' untranslated region of this gene contains 5-37 copies of a CTG trinucleotide repeat. Expansion of this unstable motif to 50-5,000 copies causes myotonic dystrophy type I, which increases in severity with increasing repeat element copy number. Repeat expansion is associated with condensation of local chromatin structure that disrupts the expression of genes in this region. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. [provided by RefSeq
