PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • a short N terminal region
  • a coiled-coil region and the flanking disulfide ring
  • a single N linked glycosylation site in the middle of the coiled-coil region
  • a unique high-affinity, nonsubstrate binding site for thrombin, which seems critical for the expression of the antithrombin activity that develops during fibrin formation
  • a C terminal apparently globular region with an extension missing in beta chain and participation in intermolecular cross-linking
    • conjugated GlycoP
    mono polymer heteromer , hexamer
    isoforms Precursor cleaved by thrombin to form fibrin and various cleavage products of fibrinogen and fibrin

    basic FUNCTION
  • playing a role in blood clots and other responses to injury (fibrin)
  • regulating cell adhesion and spreading (various cleavage products of fibrinogen and fibrin)
  • displaying vasoconstrictor and chemotactic activities (various cleavage products of fibrinogen and fibrin)
  • being mitogens for several cell types (various cleavage products of fibrinogen and fibrin)
  • involved in regulation of blood pressure
  • acting as a cofactor in platelet aggregation
  • yielding monomers that polymerize into fibrin
    • CELLULAR PROCESS cell life, proliferation/growth
    PHYSIOLOGICAL PROCESS coagulation/hemostasis
