| - | [[http://www.uniprot.org/uniprot/ITB3_HUMAN ITB3_HUMAN]] Defects in ITGB3 are a cause of Glanzmann thrombasthenia (GT) [MIM:[http://omim.org/entry/273800 273800]]; also known as thrombasthenia of Glanzmann and Naegeli. GT is the most common inherited disease of platelets. It is an autosomal recessive disorder characterized by mucocutaneous bleeding of mild-to-moderate severity and the inability of this integrin to recognize macromolecular or synthetic peptide ligands. GT has been classified clinically into types I and II. In type I, platelets show absence of the glycoprotein IIb/beta-3 complexes at their surface and lack fibrinogen and clot retraction capability. In type II, the platelets express the glycoprotein IIb/beta-3 complex at reduced levels (5-20% controls), have detectable amounts of fibrinogen, and have low or moderate clot retraction capability. The platelets of GT 'variants' have normal or near normal (60-100%) expression of dysfunctional receptors.<ref>PMID:2392682</ref> <ref>PMID:1371279</ref> <ref>PMID:1602006</ref> <ref>PMID:1438206</ref> <ref>PMID:8781422</ref> <ref>PMID:9376589</ref> <ref>PMID:9215749</ref> <ref>PMID:9790984</ref> <ref>PMID:9684783</ref> <ref>PMID:10233432</ref> <ref>PMID:11588040</ref> <ref>PMID:11897046</ref> <ref>PMID:12083483</ref> <ref>PMID:12353082</ref> <ref>PMID:15583747</ref> <ref>PMID:15634267</ref> <ref>PMID:15748237</ref> | ||

| - | [ | + | [https://www.uniprot.org/uniprot/ITAV_HUMAN ITAV_HUMAN] The alpha-V integrins are receptors for vitronectin, cytotactin, fibronectin, fibrinogen, laminin, matrix metalloproteinase-2, osteopontin, osteomodulin, prothrombin, thrombospondin and vWF. They recognize the sequence R-G-D in a wide array of ligands. In case of HIV-1 infection, the interaction with extracellular viral Tat protein seems to enhance angiogenesis in Kaposi's sarcoma lesions. |
