DXO decapping exoribonuclease [Homo sapiens (human)] - Gene

Summary

Official Symbol: DXOprovided by HGNC
Official Full Name: decapping exoribonucleaseprovided by HGNC
Primary source: HGNC:HGNC:2992
See related: Ensembl:ENSG00000204348 MIM:605996; AllianceGenome:HGNC:2992
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: NG6; RAI1; DOM3L; DOM3Z
Summary: This gene localizes to the major histocompatibility complex (MHC) class III region on chromosome 6. The function of its protein product is unknown, but its ubiquitous expression and conservation in both simple and complex eukaryotes suggests that this may be a housekeeping gene. [provided by RefSeq, Jul 2008]
Expression: Ubiquitous expression in testis (RPKM 17.8), adrenal (RPKM 16.9) and 25 other tissues See more

What's a GeneRIF?

DOM3Z limits both miR-122-dependent and miR-122-independent Hepatitis C RNA accumulation.
Title: miR-122 does not impact recognition of the HCV genome by innate sensors of RNA but rather protects the 5' end from the cellular pyrophosphatases, DOM3Z and DUSP11.
Study showed that DXO is a multifunctional enzyme that possesses both decapping and 5'-3' exoribonuclease activities toward non-2'-O-methylated RNA transcripts. DXO is directly involved in the mRNA quality control mechanism by degrading mRNAs with abnormal cap structures.
Title: 2'-O-methylation of the mRNA cap protects RNAs from decapping and degradation by DXO.
Observational study of gene-disease association, gene-environment interaction, and pharmacogenomic / toxicogenomic. (HuGE Navigator)
Title: Variation at the NFATC2 locus increases the risk of thiazolidinedione-induced edema in the Diabetes REduction Assessment with ramipril and rosiglitazone Medication (DREAM) study.
Observational study of gene-disease association. (HuGE Navigator)
Title: Gene-centric association signals for lipids and apolipoproteins identified via the HumanCVD BeadChip.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
