Comments
ADAR deaminates adenosines to produce inosines within RNAs, thereby changing the coding properties of an mRNA and altering the functional role of a gene product. ADAR1, ADAR2, and ADAR3 are mammalian members of ADAR family. They share similar domain structures including two or three repeats of a 70-aa dsRNA binding motifs followed by a highly conserved catalytic domain near the C-terminus. Unique to the ADAR1 gene locus is the presence of both constitutive and interferon-induced promoters that produces transcripts with different first exon. The interferon-induced form iADAR1 is extended by 295 aa at the N-terminus compared to the constitutively expressed form. This extra 295 aa encompasses a 65-aa domain Zα, which binds to DNA and dsRNA in a Z conformation. In addition, a functional NES is present in the N-terminus near 125-136.

User Input
Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus. Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
