Summary: Predicted to enable carboxylic ester hydrolase activity and protein homodimerization activity. Involved in negative regulation of superoxide anion generation. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and liver and biliary system.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
