Figure 1. PARP13 domain structure.

Figure 1

PARP13.1 and PARP13.2 are the two major isoforms of PARP13 in humans. Both contain four CCCH-type RNA-binding zinc fingers (red) and a WWE domain predicted to bind poly(ADP-ribose) (dark blue). PARP13.1 also contains a catalytically inactive PARP domain (green). Three additional predicted isoforms of PARP13 are shown below.
