Novel adenosine-to-guanine (A→G) editing observed in adenosine deaminase that acts on RNA 2 (ADAR2) gene transcripts from the control and activated T cells. (a, c, e, g, i) The normal sequence. Normal counterparts of A→G mutated bases at the positions −48, −45, −28, +46 and +69 in different clones are indicated with dots. (b, d, f, h, j) Edited bases at positions −48, −45, −28, +46 and +69, respectively, in different recombinant clones. All edited bases are indicated with arrows. All sequences represent sense strands.
