General annotation (Comments)

Function

Is a potent activator of prothrombin (F2). Does not elicit any hemorrhagic response. Barely inhibits collagen-induced platelet aggregation. Binds neither collagen, nor the jararhagin-monoclonal antibody MAJar3. Hydrolyzes the Aalpha-chain of fibrin and fibrinogen, without affecting the Bbeta- and gamma-chains. Is capable of triggering endothelial proinflammatory and procoagulant cell responses, but fails to trigger apoptosis. Induces von Willebrand factor release, and the expression of both ICAM1 and E-selectin (SELE) (without increase in VCAM1) in endothelial cells (HUVEC). Is also able to up-regulate the synthesis of the coagulation factor TF (F3). Enhances nitric oxide (NO) generation, prostacyclin production and interleukin-8 release By similarity.

Cofactor

Binds 1 zinc ion By similarity.

Binds 2 calcium ions By similarity.

Enzyme regulation

Inhibited by EDTA and O-phenanthroline. Not inhibited by PMSF, benzamidine, irreversible serine-proteinase inhibitors and cysteine proteinase inhibitor E-64 By similarity.

Subunit structure

Monomer By similarity.

Subcellular location

Secreted By similarity.

Tissue specificity

Expressed by the venom gland.

Sequence similarities

Belongs to the venom metalloproteinase (M12B) family. P-III subfamily.

Contains 1 disintegrin domain.
