Expression levels of Adarb1—encoding for ADAR2 that catalyzes Flna mRNA A-to-I deamination (Stulić and Jantsch, 2013)—did neither correlate with Flna expression nor editing levels and remained low but stably expressed during colitis (Fig. 7 B lower panel and Fig. S5 F). Here, ADARB1 is linked to colitis.
