Abstract

This report describes the cloning of a human cDNA that encodes a new protein (Txl, Thioredoxin-like) that belongs to the expanding family of thioredoxins based on sequence comparison of the deduced amino acid sequence. This cDNA, with a total length of 1278 bp, consists of 205 bp of 5'-untranslated sequence (including an in frame stop codon), an open reading frame of 870 bp and a 203 bp fragment of 3'-untranslated sequence. The coding sequence predicts a protein of 289 amino acids with two distinct domains: an N-terminal domain of 105 residues homologous to the rest of mammalian thioredoxins containing the conserved active site (CGPC) and a C-terminal domain of 184 residues with no homology with any other protein in the database. Northern blot analysis indicates that the txl probe hybridizes to a 1.3 Kb mRNA and is ubiquitously expressed in human tissues with the highest expression in stomach, testis and bone marrow.
