摘要：

The TRAX gene encodes a Translin-associated 33-kDa protein partner, TRAX. The TRAX protein has extensive amino acid homology with Translin, and contains bipartite nuclear targeting sequences, suggesting a possible role in the selective nuclear transport of Translin lacking any nuclear targeting motifs. In the present study, genomic clones of the human TRAX gene were isolated to determine the complete genomic organization. The genomic structure of the human TRAX gene was similar to that of the human Translin gene, consisting of six exons and five introns, encompassing approximately 27 kb in genomic DNA. Northern blot analysis revealed a predominant transcript of approximately 2.7 kb, and its distribution in various tissues was like that of Translin. Chromosomal mapping by fluorescence in situ hybridization (FISH) analysis allowed localization of the TRAX gene to human chromosome 1q41.
