Phylogenetic tree of ARS proteins. Human ARSE [GenGank:NP_000038] was used as a seed to search the GenBank NR database for orthologs and an approximate maximum-likelihood tree was generated. The putative ARS family gene downregulated in the Atrx-null forebrain clusters closely with rat ARSE but with the ARSD proteins. Entries are annotated with species, chromosome (where known) and GenBank Accession number.
