At2g35510: SRO1 (SIMILAR TO RCD ONE 1)
Encodes a WWE domain-containing protein with 76% similarity to RCD1. The protein also contains a PARP signature upstream of the C-terminal protein interaction domain. The PARP signature may bind NAD and attach the ADP-ribose-moiety from NAD to the target molecule. Its presence suggests a role for the protein in ADP ribosylation.
