Eukaryotic tRNAs are transcribed, processed and exported from the nucleus to the cytoplasm to participate in protein biosynthesis. A variant of human gene for tRNA(Val), HtV4, is not processed neither its 5'- nor its 3'-flanking sequences. By RT-PCR analysis and in situ hybridization, we demonstrated that the HtV4 was constitutively expressed without processing, and localized in the nucleus in HeLa cells.
