iso-ADP ribose 

iso-ADP ribose is the small-molecule ligand for protein nucleic acid modification, comprising parts of two consecutive ADP-ribosyl units within the PAR chain. iso-ADP ribose specifically binds WWE, FHA and OB-fold domains, enabling PAR-dependent functional responses like ubiquitylation and supporting DNA damage signaling and repair. iso-ADP ribose can be used for cancer research^[1].

iso-ADP ribose specifically binds WWE domains in specific human proteins with sub-micromolar affinity, enabling PAR-dependent functional responses like ubiquitylation^[1].
iso-ADP ribose specifically binds FHA domains of human APTX and PNKP to support DNA damage signaling and repair^[1].
iso-ADP ribose specifically binds OB-fold domains of human SSB1 and BRCA2 to mediate early recruitment to DNA break sites^[1].
