Mouse ASAHL/N-acylethanolamine-hydrolyzing Acid A Antibody

The mouse ASAHL gene encodes N-acylethanolamine-hydrolyzing Acid Amidase (NAAA), a fatty acid amidase with maximal activity at acidic pH (1). NAAA hydrolyzes a number of N-acyl ethanolamines, including N-myristoyl-, N-stearoyl-, N-oleoyl-, and N-arachidonoyl, but is most active against N-palmitoylethanolamine (2). NAAA is a member of the choloylglycine hydrolase family of enzymes, and is structurally similar to acid ceramidase (1). NAAA is both a lysosomal and a secreted enzyme, and like acid ceramidase, has been observed to be proteolytically processed during maturation (1). Through its amidase activity, ASAHL may play a role in the termination of the actions of a variety of N-acylethanolamides (3). NAAA can be distinguished from anandamide amidohydrolase by its lack of inhibition by methyl arachidonoyl fluorophosphonate (2).
