..As originally reported for rat ADAR3 or RED2, purified ADAR3 proteins could not edit GluR-B RNA at the "Q/R" site, the "R/G" site, ..

..In mammals, two such A-to-I RNA editases are RED1, which edits some serotonin and glutamate receptors, and RED2, with unidentified substrates...

..These data suggest that the interaction of gp120 with CD4 or CXCR4 is required for efficient inhibition of ADA binding to CD26, although in the presence of CXCR4 the interaction of gp120 with CD4 may be dispensable...

..The physical association of CXCR4 and CD26, direct or part of a supramolecular structure, suggests a role on the function of the immune system and the pathophysiology of HIV infection...
