Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro255 of human PAPSS1 protein. Antibodies are purified by peptide affinity chromatography.
Background
PAPS Synthase 1 and 2 (PAPSS1, PAPSS2) are bifunctional enzymes with both ATP sulfurylase and APS kinase activity. They mediate two reactions to generate 3'-phosphoadenosine-5'-phosphosulfate (PAPS), a critical intermediate in the sulfate activation pathway. PAPS is the sulfate donor co-substrate for all sulfotransferase (SULT) enzymes and is required to catalyze the sulfate conjugation of many endogenous and exogenous compounds (1,2). For example, PAPSS1 and PAPSS2 are responsible for catalyzing the sulfation of steroid hormones, which increases their water solubility and reduces their biological activity, suggesting modulation of PAPS synthases as a possible avenue for treatment of hormone-dependent cancers (3). Inhibition of PAPSS1 was also shown to increase the sensitivity of some cancer cell lines to DNA-damage agents both in vitro and in vivo (4,5), suggesting further potential utility for PAPS synthase inhibitors in cancer therapy.
Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
