Function

[IXXB_PROFL] When linked to subunit A of IX/X-bp, anticoagulant protein which binds to the gamma-carboxyglutamic acid-domain regions of factors IX (F9) and factor X (10) in the presence of calcium with a 1 to 1 stoichiometry.[1] [2] [3] When linked to subunit A of IX-bp, anticoagulant protein which binds to the gamma-carboxyglutamic acid-domain regions of factor IX (but not to factor X) in the presence of calcium with a 1 to 1 stoichiometry.[4] [5] [6]

Publication Abstract from PubMed

Coagulation factors IX/X-binding protein is an intertwined dimer with a central loop projecting into the adjoining subunit. Excluding this loop, each subunit has a fold similar to rat mannose-binding protein.
