At1g70440: SRO3 (SIMILAR TO RCD ONE 3)

Encodes a protein with similarity to RCD1 but without the WWE domain. The protein does have 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.
