This entry represents the first Tudor domain found in krimper protein from insects. Krimper is required for ping-pong piRNA amplification and is capable of both self-interactions and binding of the two PIWI proteins: Aub and Ago3 [1]. The ping-pong cycle is a process where the degradation of complementary target mRNA by PIWI proteins can trigger the generation of new RNA guides for the repression of transposable elements proliferation [2]. This domain is found in a region of the protein involved in the interaction and binding to Ago3, but not Aub [3].	Domain
