UniProt code: Q9DEF8.

Organism: Deinagkistrodon acutus (Hundred-pace snake) (Agkistrodon acutus).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Lepidosauria; Squamata; Bifurcata; Unidentata; Episquamata; Toxicofera; Serpentes; Colubroidea; Viperidae; Crotalinae; Deinagkistrodon.
 
Function: Anticoagulant protein which binds to the gamma- carboxyglutamic acid-domain regions of factors IX and factor X in the presence of calcium with a 1 to 1 stoichiometry. Also inhibits platelet aggregation by binding to platelet glycoprotein Ibalpha (GP1BA) and functioning as a blocker of vWF. Is devoid of hemorrhagic and lethal activities. Possesses antithrombotic and thrombolytic activities. Also hydrolyzes the Aalpha-chain of fibrinogen. Does not affect the Bbeta- chain and the gamma chain (By similarity). {ECO:0000250}.
 
Subunit: Heterodimer with subunit A of agkisacutacin or AaACP; disulfide-linked. {ECO:0000269|PubMed:11404471, ECO:0000269|Ref.5}.
Subcellular location: Secreted.
Tissue specificity: Expressed by the venom gland.
Similarity: Belongs to the snaclec family. {ECO:0000305}.
