Vwf (mouse, UniProt Q8CIZ8) - manual literature research
No deep-research provider was available for this session; this file records the
literature work done manually from cached publications (publications/PMID_*.md),
the UniProt record (Vwf-uniprot.txt) and PubMed searches. Quotes are verbatim from
the cited source.
Identity and domain architecture
- Mouse von Willebrand factor, 2813 aa precursor (Swiss-Prot Q8CIZ8; MGI:98941;
GeneID 22371). The precursor is cleaved into the propeptide "von Willebrand
antigen 2" (residues 23-763) and mature VWF (764-2813) [file:mouse/Vwf/Vwf-uniprot.txt].
- Domains: VWFD1-D4, TIL, three VWFA domains (A1 "binding site for platelet
glycoprotein Ib"; A3 "principal binding site for collagens type I and III"), VWFC
and a C-terminal cystine knot (CTCK); RGD "Cell attachment site" at 2507-2509
[file:mouse/Vwf/Vwf-uniprot.txt].
- UniProt function (by similarity to human P04275 and PMID:10930441): "it promotes
adhesion of platelets to the sites of vascular injury by forming a molecular bridge
between sub-endothelial collagen matrix and platelet-surface receptor complex
GPIb-IX-V" and "Also acts as a chaperone for coagulation factor VIII".
Mouse genetic evidence
- Vwf knockout (Denis et al. 1998) PMID:9689113; FVIII reduced PMID:9689113. Abstract only in cache.
- Arteriolar thrombosis (Ni et al. 2000, full text) PMID:10930441
and PMID:10930441.
- Venous platelet adhesion to VWF secreted on stimulated endothelium via GPIbalpha
PMID:11071623.
- Laser injury: VWF is needed for platelet accumulation but not platelet activation
PMID:17380206.
- VWF-GPIb-V-IX triggers platelet procoagulant activity / fibrin formation at low shear,
impaired with Vwf-/- mouse plasma PMID:21037087.
- Weibel-Palade body formation requires VWF PMID:11274431; leukocyte rolling is reduced in Vwf-/- mice
PMID:11274431.
- Atherosclerosis reduced in LDLR-/-Vwf-/- mice PMID:11520791.
- Tspan18-knockout mice: histamine-induced VWF release reduced (VWF measured as a
readout) PMID:30573509.
- MAGP1 (Mfap2) binds VWF PMID:18281502.
Mechanism (from human VWF literature, cached)
Problem references in GOA
- PMID:7854452 (Schmidt et al. 1995) is the Hgf (scatter factor) knockout paper; the
GOA rows (liver/placenta development) carry the Hgf allele MGI:1857656
(Hgf, checked on the MGI allele page) in With/From.
- PMID:8562500 is about CD24 (heat-stable antigen) as a P-selectin ligand; the abstract
does not mention VWF.
- PMID:20097747 (requested for this session) is a rat myocardial infarction study in
which an anti-vWF antibody is only an endothelial/capillary marker PMID:20097747; it gives no information about Vwf function.
