[[http://www.uniprot.org/uniprot/XXLT1_MOUSE XXLT1_MOUSE]] Alpha-1,3-xylosyltransferase, which elongates the O-linked xylose-glucose disaccharide attached to EGF-like repeats in the extracellular domain of Notch proteins by catalyzing the addition of the second xylose. [[http://www.uniprot.org/uniprot/FA9_HUMAN FA9_HUMAN]] Factor IX is a vitamin K-dependent plasma protein that participates in the intrinsic pathway of blood coagulation by converting factor X to its active form in the presence of Ca(2+) ions, phospholipids, and factor VIIIa.
