Species :Dog
Tag :GST
Expression System:Sf9 insect cells using baculovirus
Sequence :Full Length
Genbank Number :XM_548143
Alternative Name(s) :PENT; PNMTase
Formulation :Recombinant protein stored in 50mM Tris-HCl, pH 7.5, 150mM NaCl, 10mM glutathione, 0.1mM EDTA, 0.25mM DTT, 25% glycerol.

Scientific Background :Phenylethanolamine N-methyltransferase (PNMT) catalyzes the biosynthesis of adrenaline though methylation of phenylethanolamine (1). PNMT gene is reported to be involved in various human diseases including early-onset Alzheimer disease (2), Parkinson's disease (3), and multiple sclerosis (4). Expression of PNMT can be stimulated by nicotine (5).
