The grc-G/C region of the rat is homologous to the Q/TL region of the mouse, and deletions in this region are associated with fetal mortality, developmental defects, and decreased resistance to cancer. Several cosmids spanning approximately 45 kilobases of this region were analyzed for their class I loci, using a mouse general class I probe (pAG64c), grc-specific probes (pGRC1.4, pGRC1.7), and four probes derived from the TL-like locus RT1.N1. The results showed that TL-like genes other than RT1.N1 exist in the rat: a duplicated gene, RT1.N2, was identified, sequenced, and shown to be 99.3% similar to RT1.N1; and a third TL-like gene, RT1.N3, was isolated from a cDNA library, sequenced, and shown to be 92.8% similar to RT1.N1. These observations suggest that the rat TL-like loci are duplicated and that there is more than one cluster of these duplicated genes. The TL-like genes are transcribed predominantly in the thymus, except in grc- strains, and their level of transcription increases during fetal life and reaches its maximum at birth. Finally, a cosmid that appears to identify the end of the deletion in grc- strains was identified.
