Contains a PAM2-like motif, which seems to be involved in the binding to the PABC/CTC domain of PAB proteins. May be due to a competing acceptor splice site. The predicted gene has been split into 3 genes: At4g14270, At4g14272 and At4g14276. The predicted gene has been split into 3 genes: At4g14270, At4g14272 and At4g14276.
