產(chǎn)品介紹 This gene encodes the enzyme responsible for RNA editing by site-specific deamination of adenosines. This enzyme destabilizes double-stranded RNA through conversion of adenosine to inosine. Mutations in this gene have been associated with dyschromatosis symmetrica hereditaria. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2010]
Function:
Converts multiple adenosines to inosines and creates I/U mismatched base pairs in double-helical RNA substrates without apparent sequence specificity. Has been found to modify more frequently adenosines in AU-rich regions, probably due to the relative ease of melting A/U base pairs as compared to G/C pairs. Functions to modify viral RNA genomes and may be responsible for hypermutation of certain negative-stranded viruses. Edits the messenger RNAs for glutamate receptor (GLUR) subunits by site-selective adenosine deamination. Produces low-level editing at the GLUR-B Q/R site, but edits efficiently at the R/G site and HOTSPOT1. Binds to short interfering RNAs (siRNA) without editing them and suppresses siRNA-mediated RNA interference. Binds to ILF3/NF90 and up-regulates ILF3-mediated gene expression.
Subunit:
Homodimer. Isoform 1 interacts with ILF2/NF45 and ILF3/NF90.
Subcellular Location:
Cytoplasm. Nucleus, nucleolus. Isoform 1: Cytoplasm. Note=Found predominantly in cytoplasm but appears to shuttle between the cytoplasm and nucleus. Isoform 5: Nucleus, nucleolus.
Tissue Specificity:
Ubiquitously expressed, highest levels were found in brain and lung.
Post-translational modifications:
Sumoylation reduces RNA-editing activity.
DISEASE:
Defects in ADAR are a cause of dyschromatosis symmetrical hereditaria (DSH) [MIM:127400]; also known as reticulate acropigmentation of Dohi. DSH is a pigmentary genodermatosis of autosomal dominant inheritance characterized by a mixture of hyperpigmented and hypopigmented macules distributed on the dorsal parts of the hands and feet.
Similarity:
Contains 1 A to I editase domain.
Contains 2 DRADA
