Summaries for ADARB2 Gene

Entrez Gene Summary for ADARB2 Gene

  • This gene encodes a member of the double-stranded RNA adenosine deaminase family of RNA-editing enzymes and may play a regulatory role in RNA editing. [provided by RefSeq, Jul 2008]

GeneCards Summary for ADARB2 Gene

ADARB2 (Adenosine Deaminase, RNA Specific B2 (Inactive)) is a Protein Coding gene. Among its related pathways are Pyrimidine metabolism (KEGG). GO annotations related to this gene include poly(A) RNA binding and double-stranded RNA binding. An important paralog of this gene is ADAR.

UniProtKB/Swiss-Prot for ADARB2 Gene

  • Lacks editing activity. It prevents the binding of other ADAR enzymes to targets in vitro, and decreases the efficiency of these enzymes. Capable of binding to dsRNA but also to ssRNA.
