CC   -!- FUNCTION: Could inhibit the oxidative burst of leukocytes and
CC       neutralize the secondary products of lipid peroxidation, thus providing
CC       the resistance of these parasites to immune effector mechanisms and
CC       their persistence in the mammalian host. It may also be involved in the
CC       formation of cross-linking residues such as dityrosine, trityrosine and
CC       isotrityrosine identified in cuticular collagen. Highly cross-linked
CC       external cortex may also serve to protect the parasite from immune
CC       attack.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 glutathione + H2O2 = glutathione disulfide + 2 H2O;
CC         Xref=Rhea:RHEA:16833, ChEBI:CHEBI:15377, ChEBI:CHEBI:16240,
CC         ChEBI:CHEBI:57925, ChEBI:CHEBI:58297; EC=1.11.1.9;
CC   -!- SUBUNIT: Homotetramer.
CC   -!- SUBCELLULAR LOCATION: Secreted. Note=Secreted into the cuticle and
CC       ultimately released into the medium.
CC   -!- DEVELOPMENTAL STAGE: Up-regulated in the third stage larvae following
CC       infection of host. Concomitant synthesis occurs at a high level through
CC       the adult stage. Not detected in microfilariae.
CC   -!- SIMILARITY: Belongs to the glutathione peroxidase family.
CC       {ECO:0000305}.
