Summaries for F11 Gene

Entrez Gene Summary for F11 Gene

  • This gene encodes coagulation factor XI of the blood coagulation cascade. This protein is present in plasma as a zymogen, which is a unique plasma coagulation enzyme because it exists as a homodimer consisting of two identical polypeptide chains linked by disulfide bonds. During activation of the plasma factor XI, an internal peptide bond is cleaved by factor XIIa (or XII) in each of the two chains, resulting in activated factor XIa, a serine protease composed of two heavy and two light chains held together by disulfide bonds. This activated plasma factor XI triggers the middle phase of the intrisic pathway of blood coagulation by activating factor IX. Defects in this factor lead to Rosenthal syndrome, a blood coagulation abnormality. [provided by RefSeq, Jul 2008]

Post-translational modifications for F11 Gene

  • Activated by factor XIIa (or XII), which cleaves each polypeptide after Arg-387 into the light chain, which contains the active site, and the heavy chain, which associates with high molecular weight (HMW) kininogen
  • N-glycosylated on both chains. N-glycosylated sites mainly consist of nonfucosylated sialylated biantennary (in high abundance) and/or triantennary (in low abundance) complex structures. Glycosylation at Asn-163 uses a rare non-canonical Asn-X-Cys glycosite.
  • Glycosylation at Asn 90, Asn 126, Asn 163, Asn 353, Asn 450, and Asn 491
