Abstract: The XRN2 gene (XRN2a) is the human homologue of the Saccharomyces cerevisiae RAT1 gene, which encodes a nuclear 5'-->3' exoribonuclease, and is essential for RNA metabolism and cell viability. Xrn2p/Rat1p, product of XRN2/RAT1 gene, functions in the mRNA degradation and processing of rRNAs and small nucleolar RNAs (snoRNAs) in the nucleus. Here we describe the cloning and characterization of a novel splice variant of the human XRN2 gene (XRN2b). The 3271-bp cDNA encodes a putative protein with 907 amino acid residues, which shares high homology with mouse DHM1 protein. RT-PCR analysis showed that XRN2b was mainly expressed in blood leukocyte tissue, while XRN2a was detected in several human tissues and in human tumor tissues.FAU - Li, Jix.
