This family includes the two characterised human gamma-interferon-inducible lysosomal thiol reductase (GILT) sequences: Swiss:P13284 [1] and Swiss:Q9UL08 [2]. It also contains several other eukaryotic putative proteins with similarity to GILT [3]. The aligned region contains three conserved cysteine residues. In addition, the two GILT sequences possess a C-X(2)-C motif that is shared by some of the other sequences in the family. This motif is thought to be associated with disulphide bond reduction.
