cDNA sequences obtained from polymerase chain reaction products of reverse-transcribed RNA from sheep thymus showed the presence of a large number of members of the TRDV1 gene family. Some are TRDV1 genes also found in peripheral blood lymphocytes, while four genes had not been described so far. The cDNA sequences also showed extensive junctional diversity and a preferential usage of the three TRDJ elements. We characterized the genomic organization of the sheep TRDJ locus and detected a correlation between the nonrandom usage of TRDJ elements during development and their chromosomal order.

Abstract
cDNA sequences obtained from polymerase chain reaction products of reverse-transcribed RNA from sheep thymus showed the presence of a large number of members of the TRDV1 gene family. Some are TRDV1 genes also found in peripheral blood lymphocytes, while four genes had not been described so far. The cDNA sequences also showed extensive junctional diversity and a preferential usage of the three TRDJ elements. We characterized the genomic organization of the sheep TRDJ locus and detected a correlation between the nonrandom usage of TRDJ elements during development and their chromosomal order.File in questo prodotto:
