(A) Domain architecture of ARTD11, ARTD10, and the chimeric protein (Chimera) created by fusing the ARTD11 n-terminus to the ARTD10cat domain.
(B) Pie chart representing the total MARylated protein targets identified via LC-MS/MS for the chimeric protein. Shared protein targets are indicated by the protein schematics depicted in (A). Shared protein targets were identified based on their presence in at least one of the IG-ARTD10 or IG-ARTD11 LC-MS/MS replicates.
(D) Immunoblot detection of select LC-MS/MS identified ARTD targets (GFP-ARTD, UBE3C, XPO5, NXF1, NUP98, NAGK, WRIP1) following NeutrAvidin enrichment. Overall MARylation levels were determined using streptavidin-HRP (Biotin). ARTD10-specific, ARTD11-specific, ARTD11-WWE dependent, and shared chimera targets are indicated to the left.
