Zinc metalloproteinase oxiagin

Gene

Organism
Naja oxiana (Central Asian cobra) (Oxus cobra)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Snake venom metalloproteinase that inhibits the classical complement pathway dose-dependently. It acts by binding to carbohydrates of IgG within the antibody-sensitized sheep erythrocytes (EA) complex, and thus prevents interaction of component C2 with immobilized C4b. Also induces cation-independent hemagglutination that can be prevented by D-galactose pretreatment.1 Publication

Miscellaneous

Does not show proteolytic activity on rabbit IgG, human C3 and C4 complement components, fibrinogen, beta-casein, hemoglobin, ferritin, myoglobin, chymotrypsinogen, and melittin.1 Publication
