APTX - aprataxin Gene
Also Known as AOA; AOA1; AXA1; EAOH; EOAHA; FHA-HIT
Species: Homo sapiens
About APTX
This gene has 56 transcripts (splice variants), 203 orthologues, 1 paralogue and is associated with 3 phenotypes. Ubiquitous expression in kidney (RPKM 2.7), testis (RPKM 2.3) and 25 other tissues.
Summary
This gene encodes a member of the histidine triad (HIT) superfamily. The encoded protein may play a role in single-stranded DNA repair through its nucleotide-binding activity and its diadenosine polyphosphate hydrolase activity. Mutations in this gene have been associated with ataxia-ocular apraxia. Alternatively spliced transcript variants have been identified for this gene.[provided by RefSeq, Aug 2010]
