</p><p><b>Basigin</b> (auch: <i>extracellular matrix metalloproteinase inducer</i>, kurz <b>EMMPRIN</b>) ist ein <a href="Glykoprotein" class="mw-redirect" title="Glykoprotein">Glykoprotein</a> in der <a href="Zellmembran" title="Zellmembran">Zellmembran</a> von <a href="Epithel" title="Epithel">Epithelzellen</a> der <a href="Wirbeltiere" title="Wirbeltiere">Wirbeltiere</a>. Es übt Funktionen unter anderem im <a href="Kohlenhydrate" title="Kohlenhydrate">Kohlenhydrat</a>-<a href="Stoffwechsel" title="Stoffwechsel">Stoffwechsel</a> und bei der <a href="Signaltransduktion" title="Signaltransduktion">Signaltransduktion</a> des <a href="Immunsystem" title="Immunsystem">Immunsystems</a> aus. Basigin trägt eine <a href="Immunglobulin" class="mw-redirect" title="Immunglobulin">Immunglobulin</a> (Ig)-<a href="Proteindom%C3%A4ne" title="Proteindomäne">Proteindomäne</a> und ist Determinante des Ok-<a href="Blutgruppe" title="Blutgruppe">Blutgruppensystems</a>. Beim Menschen wird es hauptsächlich im Gefäßepithel und in malignen <a href="Gliom" title="Gliom">Gliomen</a> exprimiert.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>
</p><p>Basigin ist für die Lokalisierung der Monocarboxylat-Transporter <a href="Monocarboxylat-Transporter_1" title="Monocarboxylat-Transporter 1">MCT1</a>, MCT4 und MCT12 zuständig, deren anschließende Transportaktivität ohne Bindung an Basigin unmöglich ist. Basigin ist damit unentbehrlich für den Austausch von <a href="Lactat" class="mw-redirect" title="Lactat">Lactat</a> zwischen den Zellen.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>
</p><p>Mithilfe der Ig-Domäne bindet Basigin der einen Zelle an Basigin einer benachbarten Zelle und agiert so als <a href="Zelladh%C3%A4sionsmolek%C3%BCl" title="Zelladhäsionsmolekül">Zelladhäsionsmolekül</a>. Basigin bindet weiterhin <a href="Integrine" title="Integrine">Integrine</a>, Cyclophiline, <a href="Caveolin" title="Caveolin">Caveolin</a>-1 und <a href="Annexine" title="Annexine">Annexin&nbsp;II</a>. Seine zytosolische Domäne induziert die Expression von <a href="Matrix-Metalloproteasen" title="Matrix-Metalloproteasen">Matrix-Metalloproteasen</a> (MMP) und ist dadurch Teil der <a href="Angiogenese" title="Angiogenese">Angiogenese</a>, <a href="Zellproliferation" title="Zellproliferation">Zellproliferation</a>, des <a href="Energiestoffwechsel" title="Energiestoffwechsel">Energiestoffwechsels</a>, der <a href="Zellmigration" title="Zellmigration">Zellmigration</a> und der Zell<a href="Motilit%C3%A4t" title="Motilität">motilität</a>.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup>
</p><p>Neben seiner physiologischen Bedeutung spielt Basigin eine wichtige Rolle in der Entstehung der durch <a href="Plasmodium_falciparum" title="Plasmodium falciparum">Plasmodium falciparum</a> ausgelösten <a href="Malaria" title="Malaria">Malaria</a> tropica. Der Parasit benutzt Basigin als <a href="Rezeptor_(Biochemie)" title="Rezeptor (Biochemie)">Rezeptor</a>, um an <a href="Erythrozyt" title="Erythrozyt">Erythrozyten</a> zu binden und in sie einzudringen.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> Möglicherweise dient Basigin auch dem Coronavirus <a href="SARS-CoV-2" title="SARS-CoV-2">SARS-CoV-2</a> als eine Eintrittspforte in Wirtszellen (neben <a href="Angiotensin-konvertierendes_Enzym_2" title="Angiotensin-konvertierendes Enzym 2">ACE2</a>).<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> Ein gegen CD147 gerichteter Antikörper, Meplazumab wurde gegen die COVID-19 Pneumonie an Patienten erfolgreich getestet.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup>
