Popis: | The CD9 antigen was originally described as a 24-kDa molecule present on B-lineage-derived acute lymphoblastic leukemia cells and developing B lymphocytes. Platelets also express a large amount of CD9 antigen and can be activated by CD9 antibodies. We report here the structure of the CD9 gene, which is composed of 8 exons spanning more than 20 kb. There is no TATA or CAAT box in the 5′-flanking domain of the CD9 gene, but a 120-bp region extremely rich in C and G (88%) contains several Sp1 binding sites and a consensus site for the binding of zinc-finger proteins of the Krox/EGR family. The CD9 antigen belongs to a new cell surface protein family. The organization of its gene closely resembles the organization of the genes for two other members of this protein family, TAPA1 and CD63, which share with CD9 respectively 45 and 25% identity at the amino acid level. |
