DESCRIPTION: RecName: Full=Alkylated DNA repair protein alkB homolog 8; EC=1.14.11.-; AltName: Full=Probable alpha-ketoglutarate-dependent dioxygenase ABH8; AltName: Full=S-adenosyl-L-methionine-dependent tRNA methyltransferase ABH8; AltName: Full=tRNA (carboxymethyluridine(34)-5-O)-methyltransferase ABH8; EC=;
FUNCTION: Catalyzes the methylation of 5-carboxymethyl uridine to 5-methylcarboxymethyl uridine at the wobble position of the anticodon loop in tRNA. Catalyzes the last step in the formation of 5-methylcarboxymethyl uridine at the wobble position of the anticodon loop in target tRNA. Has a preference for tRNA(Arg) and tRNA(Glu), and does not bind tRNA(Lys). Required for normal survival after DNA damage. May inhibit apoptosis and promote cell survival and angiogenesis.
CATALYTIC ACTIVITY: S-adenosyl-L-methionine + carboxymethyluridine(34) in tRNA = S-adenosyl-L-homocysteine + 5- (2-methoxy-2-oxoethyl)uridine(34) in tRNA.
SUBUNIT: Interacts with TRMT112.
SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=Predominantly cytoplasmic.
TISSUE SPECIFICITY: Widely expressed, with highest expression in spleen, followed by pancreas and lung.
INDUCTION: Up-regulated after DNA damage. Induction is mediated via ATM.
SIMILARITY: Belongs to the alkB family.
SIMILARITY: Contains 1 Fe2OG dioxygenase domain.
SIMILARITY: Contains 1 RRM (RNA recognition motif) domain.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

ModBase Predicted Comparative 3D Structure on Q96BT7
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
