Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Factor VIII, along with calcium and phospholipid, acts as a cofactor for F9/factor IXa when it converts F10/factor X to the activated form, factor Xa.SUBUNIT Interacts with VWF/vWF. vWF binding is essential for the stabilization of F8 in circulation.INTERACTION Domain F5/8 type C 2 is responsible for phospholipid-binding and essential for factor VIII activity.PTM Sulfation on Tyr-1699 is essential for binding vWF.PTM Proteolytically cleaved by cathepsin CTSG to produce a partially activated form.DISEASE The disease is caused by variants affecting the gene represented in this entry. Of particular interest for the understanding of the function of F8 is the category of CRM (cross-reacting material) positive patients (approximately 5%) that have considerable amount of F8 in their plasma (at least 30% of normal), but the protein is non-functional; i.e. the F8 activity is much less than the plasma protein level. CRM-reduced is another category of patients in which the F8C antigen and activity are reduced to approximately the same level. Most mutations are CRM negative, and probably affect the folding and stability of the protein.DISEASE The disease is caused by variants affecting the gene represented in this entry.PHARMACEUTICAL Available under the names Kogenate (Bayer) and Recombinate (Baxter and American Home Products). Used to treat hemophilia A.SIMILARITY Belongs to the multicopper oxidase family.ONLINE INFORMATION Factor VIII entry
