Biological Activity:

UNC2170 is a selective and cell permeable methyl-lysine binding protein 53BP1 antagonist with micromolar activity. It displays >17-fold selectivity for 53BP1 as compared to other methyl-lysine (Kme) binding proteins tested. Structural studies revealed that the tert-butyl amine of UNC2170 anchors the compound in the methyl-lysine (Kme) binding pocket of 53BP1, making it competitive with endogenous Kme substrates. X-ray crystallography also demonstrated that UNC2170 binds at the interface of two tudor domains of a 53BP1 dimer. It functions as a 53BP1 antagonist in cellular lysates and shows cellular activity by suppressing class switch recombination, a process which requires a functional 53BP1 tudor domain.

How to Use:

In vitro: UNC2170 was used at 10-30 µM final concentration in various in vitro assays.
In vivo: n/a
