Summary
Multimerin is a massive, soluble protein found in platelets and in the endothelium of blood vessels. It is comprised of subunits linked by interchain disulfide bonds to form large, variably sized homomultimers. Multimerin is a factor V/Va-binding protein and may function as a carrier protein for platelet factor V. It may also have functions as an extracellular matrix or adhesive protein. Recently, patients with an unusual autosomal-dominant bleeding disorder (factor V Quebec) were found to have a deficiency of platelet multimerin. [provided by RefSeq, Jul 2008]

  • Hemostasis, organism-specific biosystem (from REACTOME)
    Hemostasis, organism-specific biosystemHemostasis is a physiological response that culminates in the arrest of bleeding from an injured vessel. Under normal conditions the vascular endothelium supports vasodilation, inhibits platelet adhe...
  • Platelet activation, signaling and aggregation, organism-specific biosystem (from REACTOME)
    Platelet activation, signaling and aggregation, organism-specific biosystemPlatelet activation begins with the initial binding of adhesive ligands and of the excitatory platelet agonists (released or generated at the sites of vascular trauma) to cognate receptors on the pla...
  • Platelet degranulation, organism-specific biosystem (from REACTOME)
    Platelet degranulation, organism-specific biosystemPlatelets function as exocytotic cells, secreting a plethora of effector molecules at sites of vascular injury. Platelets contain a number of distinguishable storage granules including alpha granules...
  • Response to elevated platelet cytosolic Ca2+, organism-specific biosystem (from REACTOME)
    Response to elevated platelet cytosolic Ca2+, organism-specific biosystemActivation of phospholipase C enzymes results in the generation of second messengers of the phosphatidylinositol pathway. The events resulting from this pathway are a rise in intracellular calcium an...

NCBI Reference Sequences (RefSeq)

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
