Carboxylesterase 5 (CES5), also known as cauxin or CES7, is a key enzyme in the carboxylesterase family, playing a crucial role in hydrolyzing ester and amide bonds. This enzyme, widely distributed in cells, particularly in mammalian livers, exhibits broad substrate specificity, ranging from small molecule esters to long-chain fatty acid esters and thioesters. Previous studies have found high concentrations of CES5 in the urine of adult male cats and within protein complexes in mammalian male epididymal fluids. Its roles may include regulating male cat pheromone levels, catalyzing lipid transfer reactions, and protecting neural tissue from drugs and xenobiotics. This recombinant protein is suitable for biological assays and is intended for research use only. At Innovative Research, we ensure reliable, consistent products that deliver consistent results.
