摘要: Substitutional RNA editing represents an important posttranscriptional enzymatic pathway for increasing genetic plasticity by permitting production of different translation products from a single genomically encoded template. One the best-characterized examples in mammals is C to U deamination nuclear apolipoprotein B (apoB) mRNA. ApoB mRNA undergoes single, site-specific cytidine event yielding edited transcript that results tissue-specific two distinct isoforms, referred as apoB100 and apoB48. Tissue- apoB mediated incompletely characterized holoenzyme containing minimal core complex consisting RNA-specific deaminase, Apobec-1 requisite cofactor, apobec-1 complementation factor (ACF). The underlying biochemical mechanisms regulating have been accelerated through development characterization physiological rodent models well knockout transgenic animal strains.
