CC   -!- FUNCTION: Anticoagulant protein. May prevent the complex of factors Xa
CC       (F10) and factor Va (F5) from binding to phospholipid surfaces and to
CC       prothrombin (F2). Also blocks the activation of factor X (F10) by
CC       factor VIIa (F7) and tissue factor (F3) as well.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
