CST, 10478S, dCK Antibody

Polyclonal Antibody for studying dCK. Validated for Western Blotting,Immunoprecipitation. Highly specific and rigorously validated in-house, dCK Antibody (CST #10478) is ready to ship. Product Usage Information Western Blotting: 1:1000 Immunoprecipitation: 1:50 Storage Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, and 50% glycerol. Store at -20°C. Do not aliquot the antibody. Protocol Available protocols: Western Blotting, Immunoprecipitation Specificity / Sensitivity dCK Antibody recognizes endogenous levels of total dCK protein. This antibody detects a doublet of unknown origin at approximately 80 kDa by western blot. Species Reactivity: Human, Mouse Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val250 of human dCK protein. Antibodies are purified by peptide affinity chromatography. Background Deoxycytidine kinase (dCK) catalyzes the rate-limiting step in the nucleoside salvage pathway. dCK phosphorylates salvaged deoxycytidine (dC) to generate deoxycytidine monophosphate (dCMP), a precursor for both deoxycytidine triphosphate (dCTP) and deoxythymidine triphosphate (dTTP) pools (1). dCK also phosphorylates deoxyadenosine (dA) and deoxyguanosine (dG) to generate dA monophosphate and dG monophosphate, respectively. Gemcitabine is an anticancer nucleoside that is a dC analog. It is a pro-drug and must be phosphorylated by dCK to an active form. dCK is phosphorylated on Ser74 by the DNA damage signaling kinases ATM and ATR, and this phosphorylation increases dCK activity (2,3).
