This is the tudor domain found in DNA repair protein crb2. Structural and functional studies of Crb2 and its mammalian homologue 53BP1 indicate that the conserved tandem-Tudor domain of 53BP1 and Crb2 preferentially interacts with H4K20me2, though it also binds to H4K20me1 [1]. Furthermore, despite low amino acid sequence similarity, Crb2 is structurally related to 53BP1 in having two tudor domains and a conserved dimethyllysine-binding pocket, and that, like 53BP1, it directly binds H4-K20me2 [2].
