A real-time PCR method for the quantitative analysis of RNA editing at specific sites.

In this study, a quantitative PCR (qPCR) method was developed to determine the A-to-I RNA editing frequencies at specific sites. The A-to-I RNA editing of nuclear transcripts exerts profound effects on the biological activities of gene products. RNA editing of nuclear gene transcripts have been shown to be developmentally regulated and tissue specific, and alternations of RNA editing activities have been observed under pathological conditions.
