CD3 is a complex of polypeptides which form part of the T cell receptor. Normal human peripheral pan T cells, express not only CD3, but the mRNA for myosin regulatory light chains MYL9, MYL12A, and MYL12B are also significantly expressed. In the Jurkat wild strain, an acute T cell leukemia cell line, CD3 on the surface and MYL9 mRNA are not expressed, while both MYL12A mRNA and MYL12B mRNA are expressed. Jurkat-I, a new clone was established by the transfection of the MYL9 gene into the Jurkat wild strain. As a result, the level of CD3 expressed on the surface of Jurkat-I cells was significantly higher than those in the Jurkat wild strain. Phorbol 12-myristate 13-acetate increased the surface CD3 levels in Jurkat wild strain cells without resulting in MYL9 gene expression, indicating that protein kinase C is partially involved in the expression of CD3 on the surface. These results suggest that surface CD3 expression proceeds through both MYL9-dependent and MYL9-independent pathways (i.e. the protein kinase C- dependent pathway) in Jurkat cells.
