Name :
Recombinant Human CES1 Protein (His Tag), HPLC-verified
Biological Activity :
Background :
CES1 encodes carboxylesterase-1, an important drug-metabolizing enzyme with high expression in the liver. Variants generated by the exchange of segments with CES1P1 complicate the genotyping of CES1. CES1 is involved in the hydrolysis of ester group-containing xenobiotic and endobiotic compounds including several essential and commonly used drugs. The individual variation in the efficacy and tolerability of many drugs metabolized by CES1 is considerable. However, it has been problematic to express recombinant CES1 in bacterial expression systems due to low solubility, with the CES1 protein being mainly expressed in inclusion bodies, accompanied by insufficient purity issues. CES1 is capable of catalyzing the hydrolysis of a wide range of therapeutic agents, toxins, and endogenous compounds. Accumulating studies have demonstrated associations between the expression and activity of CES1 and the pharmacokinetics and/or pharmacodynamics of CES1 substrate medications.
