Although Hox genes contain and are originally named because of the homeobox sequence, not all homeobox-containing genes are Hox genes (other examples include the POU genes and CDX genes). The homeobox encodes for a protein sequence called the homeodomain, which is a DNA-binding domain.
Aprataxin is a protein that in humans is encoded by the APTX gene. This gene encodes a member of the histidine triad superfamily, some of which have nucleotide-binding and diadenosine polyphosphate hydrolase activities. The encoded protein may play a role in single-stranded DNA repair. Mutations in this gene have been associated with ataxia-ocular apraxia. Multiple transcript variants encoding distinct isoforms have been identified for this gene, however, the full length nature of some variants
