The absence of factor IX activity results in the bleeding disorder hemophilia B. This absence of activity can arise either from a lack of circulating factor IX protein or mutations that decrease the activity of factor IX. This review focuses on analyzing the structure of factor IX with respect to molecular mechanisms that are at the basis of factor IX function. The proteolytic activation of factor IX to form activated factor IX(a) and subsequent structural rearrangements are insufficient to generate the fully active factor IXa. Multiple specific interactions between factor IXa, the cofactor VIIIa, and the physiological substrate factor X further alter the factor IXa structure to achieve the full enzymatic activity of factor IXa. Factor IXa also interacts with inhibitors, extravascular proteins, and cellular receptors that clear factor IX(a) from the circulation. Hemophilia B is treated by replacement of the missing factor IX by plasma-derived protein, a recombinant bioequivalent, or via gene therapy. An understanding of how the function of factor IX is tied to structure leads to modified forms of factor IX that have increased residence time in circulation, higher functional activity, protection from inhibition, and even activity in the absence of factor VIIIa. These modified forms of factor IX have the potential to significantly improve therapy for patients with hemophilia B.</p>","PeriodicalId":9102,"journal":{"name":"Blood","volume":" ","pages":"2198-2210"},"PeriodicalIF":21.0,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141598395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with array-based genotyping, whole-genome sequencing (WGS) data provide better coverage of the genome and better representation of non-European variants. To better understand the genetic landscape regulating plasma fibrinogen levels, we meta-analyzed WGS data from the National Heart, Lung, and Blood Institute's Trans-Omics for Precision Medicine (TOPMed) program (n = 32 572), with array-based genotype data from the Cohorts for Heart and Aging Research in Genomic Epidemiology Consortium (n = 131 340) imputed to the TOPMed or Haplotype Reference Consortium panel.

Although involved in processes such as inflammation, angiogenesis, and cancer metastasis, VWF is mostly known for its role in hemostasis, by acting as a chaperone protein for coagulation factor VIII (FVIII) and by contributing to the recruitment of platelets during thrombus formation. To serve its role in hemostasis, VWF needs to bind a variety of ligands, including FVIII, platelet-receptor glycoprotein Ib-α, VWF-cleaving protease ADAMTS13, subendothelial collagen, and integrin α-IIb/β-3. Importantly, interactions are differently regulated for each of these ligands. How are these binding events accomplished and coordinated? The basic structures of the domains that constitute the VWF protein are found in hundreds of other proteins of prokaryotic and eukaryotic organisms. However, the determination of the 3-dimensional structures of these domains within the VWF context and especially in complex with its ligands reveals that exclusive, VWF-specific structural adaptations have been incorporated in its domains. They provide an explanation of how VWF binds its ligands in a synchronized and timely fashion. In this review, we have focused on the domains that interact with the main ligands of VWF and discuss how elucidating the 3-dimensional structures of these domains has contributed to our understanding of how VWF function is controlled. We further detail how mutations in these domains that are associated with von Willebrand disease modulate the interaction between VWF and its ligands.</p>","PeriodicalId":9102,"journal":{"name":"Blood","volume":" ","pages":"2174-2184"},"PeriodicalIF":21.0,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141537500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
