Eigenschaften
CD81 wird von hΓ€matopoetischen, Endothel- und Epithelzellen gebildet, aber auch von hΓ€matopoetischen, neuroektodermalen und mesenchymalen Tumor-Zelllinien gebildet. Es kommt nicht in Erythrozyten, BlutplΓ€ttchen und Neutrophilen vor. CD81 ist an der Organisation der Zellmembran, am Proteintransport, an Zellfusionen und Zellkontakten beteiligt.cite-ref-vences-1-0[1] Im Immunsystem reguliert CD81 die immunologische Synapse, die Gruppierung von Rezeptoren in der Zellmembran und mindert die Immunantwort.cite-ref-vences-1-1[1] CD81 bindet an Leu-13. Weiterhin bindet es an Tspan-4,cite-ref-pmid9360996-2-0[2] CD19,cite-ref-pmid1383329-3-0[3]cite-ref-pmid7636191-4-0[4]cite-ref-pmid9804823-5-0[5] CD9,cite-ref-pmid9804823-5-1[5]cite-ref-pmid8630057-6-0[6] PTGFRN,cite-ref-pmid11278880-7-0[7]cite-ref-pmid11087758-8-0[8] CD117cite-ref-pmid12036870-9-0[9] und CD29.cite-ref-pmid10229664-10-0[10]cite-ref-pmid12175627-11-0[11] AuΓerdem bindet es an IGSF8,cite-ref-pmid11673522-12-0[12] CD316 und CD36 und bildet einen grΓΆΓeren Proteinkomplex mit CD19, CD21 und Leu-13 an der ZelloberflΓ€che von B-Zellen.cite-ref-cd81-13-0[13]
CD81 ist ein Rezeptor fΓΌr das Hepatitis-C-Viruscite-ref-14[14] und Plasmodiencite-ref-15[15]cite-ref-16[16] und verstΓ€rkt eine Infektion mit Listerien.cite-ref-vences-1-2[1] Vermutlich ist CD81 der zellulΓ€re Rezeptor fΓΌr das HCMV.cite-ref-17[17]
CD81 ist an der Regulierung des Zellwachstums von Lymphomen beteiligt und dient als Target bei der Behandlung von Tumoren.cite-ref-vences-1-3[1]
Weiterhin bindet CD81 Benzylsalicylatcite-ref-pmid22740401-18-0[18] und Terfenadin.cite-ref-pmid18560330-19-0[19]
