Adenosinedeaminase domain containing 2 (ADAD2) is phylogenetically related to a family of adenosine deaminases involved in RNA editing. It is a double-stranded RNA binding protein with unclear biological function []. ADAD2 contains a double-stranded RNA binding motif (DSRM) and a C-terminal adenosine-deaminase (editase) domain. This entry represents the DSRM of ADAD2.
