CST, 40371S, Phospho-dCK (Ser74) Antibody

Polyclonal Antibody for studying dCK (Ser74) phosphate. Validated for Western Blotting. Highly specific and rigorously validated in-house, Phospho-dCK (Ser74) Antibody (CST #40371) is ready to ship. Product Usage Information Western Blotting: 1:1000 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 Specificity / Sensitivity Phospho-dCK (Ser74) Antibody recognizes endogenous levels of dCK protein only when phosphorylated at Ser74. Species Reactivity: Human Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser74 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).
