Enzyme, ADAR (proof-read and correct mistakes in RNA)

ADAR editing enzymes are found in all multicellular animals and are conserved in sequence and protein organization. The number of ADAR genes differs between animals, ranging from three in mammals to one in Drosophila. ADAR is also alternatively spliced to generate isoforms that can differ significantly in enzymatic activity. Therefore, to study the enzyme in vitro, it is essential to have an easy and reliable method of expressing and purifying recombinant ADAR protein. To add to the complexity of RNA editing, the number of transcripts that are edited by ADARs differs in different organisms.

Long-read RNA sequencing

It is possible to quantify site‐specific RNA editing by sequencing of clones derived from RT‐PCR products.
