Clone lambda a26.1 isolated from rat olfactory epithelium contains a full-l
ength 28-kDa protein cDNA (1414 b. p.). The reconstructed protein sequence
comprises 223 aa with a calculated molecular mass of 24 630 Da. A substanti
al homology was revealed between the amino acid sequence of the 28-kDa prot
ein and those of thiol-specific antioxidants (peroxiredoxines). The 28-kDa
protein belongs to the 1Cys-subfamily of peroxiredoxines and is the first m
ember of peroxiredoxines identified in the olfactory epithelium.
