  • 功能：
    Gp-Ib, a surface membrane protein of platelets, participates in the formation of platelet plugs by binding to von Willebrand factor, which is already bound to the subendothelium.

    1. Rare variants in GP1BB are responsible for autosomal dominant macrothrombocytopenia. PMID: 28064200
    2. Data show that localization of the GP Ib-IX complex to the lipid domain is mediated by GP Ibbeta and GP IX transmembrane domains. PMID: 26203189

    11. Role of GPIbbeta in modulating vWF mediated platelet adhesion. PMID: 11816713
    12. A GP1BB missense mutation suppresses GPIb/IX complex expression and is found to cause Bernard-Soulier Syndrome in the homozygous form and giant platelets in the heterozygous form. PMID: 11816714
    13. The cysteine knot of platelet GPIb beta is critical for the interaction of GPIb beta with GPIX. PMID: 12036872
    14. PKA-mediated phosphorylation of GPIbbeta at Ser(166) negatively regulates VWF binding to GPIb-IX and is one of the mechanisms by which PKA mediates platelet inhibition PMID: 12361948
    15. The GPIb beta intracellular domain has a role in controlling the adhesive properties of the GPIb/V/IX complex through phosphorylation of GPIb beta Ser166 and point to the existence of cross-talk between the GPIb beta and GPIb alpha intracellular domains. PMID: 12522011
    16. novel hemizygous variant of Bernard-Soulier Syndrome in which Pro29 in one GPIbbeta allele is substituted by a Leu PMID: 12529755
    17. To determine the sequence in the beta3 cytoplasmic domain that is critical to integrin signaling, cell lines were established that coexpress the platelet receptor for GP1BB. PMID: 12860973
    18. identified novel GPIbbeta mutation is responsible for the Bernard-Soulier syndrome phenotype and provide an explanation for the molecular mechanism underlying the reduced platelet content of GPIb-IX complex in the heterozygous individuals studied PMID: 12958615
    19. The SEPT5 gene resides approximately 250 nucleotides 5' to the GP Ibbeta gene and has been associated with modulating exocytosis from neurons and platelets as part of a presynaptic protein complex PMID: 15213102
    20. Velocardiofacial syndrome patients have in-vitro defects in platelet function that may increase their risk of bleeding during surgery. PMID: 18064328
    21. the N1421K substitution in the VWF affects the GPIb binding site or a recognition element by a conformational change of the A1 domain. PMID: 18637125
    22. proplatelet formation in human megakaryocytes undergoes a complex spatio-temporal regulation orchestrated by adhesive proteins, GPIb-IX-V and myosin IIA PMID: 18752571
    23. novel Ser 23 Stop mutation in GPIbbeta is responsible of BSS in the studied family and hampers the complex to form on the platelets surface. PMID: 18825380
