Expression of Interferon-inducible RNA Adenosine Deaminase ADAR1 during Pathogen Infection and Mouse Embryo Development Involves Tissue-selective Promoter Utilization and Alternative Splicing

Abstract excerpt

ADAR1 (adenosine deaminase acting on RNA) is widely expressed in adult mammals and has a critical role during embryogenesis. Two size forms of ADAR1 are known that possess adenosine-to-inosine editing activity: an interferon (IFN)-inducible approximately 150-kDa protein and a constitutively expressed N-terminally truncated approximately 110-kDa protein. We defined the structure of the 5'-flanking region of the...
