| Gene product | Accession nos., RNA/gene | Editing | Repeat* | Function |
|---|---|---|---|---|
| Similar to CDK8 | AY028424/Z84480 | Intron | AluSx(+)†, AluJo(−)† | Unknown |
| NrCAM | AJ001057/AF172277 | Intron | None | Cell adhesion, axon guidance (40) |

| HsC7-I | D26599‡/AL357035 | 3′ UTR | AluSc(+), AluJb(−) | Proteasome subunit (42) |
| NADH:ubiquinone oxidoreductase subunit B14.5B | BC007323/AC023532 | 3′ UTR | AluJb(+), AluSc(−) | Mitochondrial electron transport (43) |
| Tankyrase | AF082557/AC055869 | 3′ UTR | MER53 | ADP-ribosylation of TRF (44) |
| PP2C-β | AF294792/hCG15783§ | Intron | AluY(+)¶ | Protein phosphatase (45) |
| PAR-SN | U55937/AC009696 | Noncoding | AluJo(−), AluSx(+), AluSx(+) | snoRNA host (HBII-13) (30, 31) |
(+) indicates that Alu is in sense orientation, (−) indicates antisense orientation.
Only AluSx was sequenced, but RNase T1 cleavage site was in AluJo.
mRNA sequence does not extend to edited region; a composite cDNA was constructed from expressed sequence tags to connect edited region to upstream ORF.
Accession no. for gene is from the Celera database.
There are three antisense Alus within 1 kb of this Alu but RNA was not sequenced to determine if other Alus are edited.
