The Ly-6 locus controls the expression of genes whose products in lymphoid cells are involved in the process of Ag-independent T cell activation. The Ly-6 locus contains multiple tightly linked genes which have been mapped to a specific region on murine chromosome 15. The present approach to further define the Ly-6 Ag is based on the transfection of cloned genes and identification of the expressed products by using mAb. Screening of Ly-6 related chromosomal clones revealed one that contains a gene that is closely related to yet distinct from that of the previously characterized Ly-6E.1 protein. Transfection of this chromosomal clone into COS cells shows that it contains the gene encoding Ly-6C.1 determinants. The expression of the transfected Ly-6C.1 gene is enhanced in COS cells following treatment with mouse IFN. Characterization of the DNA sequence of the Ly-6C.1 gene has established that it consists of four exons, the first of which is untranslated. Several possible regulatory elements have been identified in the putative promoter region of this gene (5' to the first exon), including a 28-base sequence closely resembling the consensus IFN-responsive sequence found in the promoter regions of other IFN-responsive genes.
