This is the first TUDOR domain found in SETDB1 enzymes (EC:2.1.1.43) in homosapiens, also known as Eggless in Drosophila [1]. In Drosophila, SetdB1 (Egg) is important for oogenesis and the silencing of chromosome 4 [2]. SET domain, bifurcated 1 (SETDB1) is a histone methyltransferase (HMT) that methylates lysine 9 on histone H3 (H3K9). The enzymatic activity of SETDB1, in association with MBD1-containing chromatin-associated factor 1 (MCAF1), converts H3K9me2 to H3K9me3 and represses subsequent transcription. SETDB1 is amplified in cancers such as melanoma and lung cancer, and increased expression of SETDB1 promotes tumorigenesis in a zebrafish melanoma model. In addition, SETDB1 is required for endogenous retrovirus silencing during early embryogenesis, inhibition of adipocyte differentiation, and differentiation of mesenchymal cells into osteoblasts [1]. The tandem Tudor domains in the N-terminal region are involved in protein-protein interactions [2]. The second tudor domain is Pfam:PF18385.
This is a Tudor domain found in histone-lysine N-methyltransferase SETDB1 proteins (EC:2.1.1.43), also known as Eggless in Drosophila [1]. In Drosophila, SetdB1 (Egg) is important for oogenesis and the silencing of chromosome 4 [2].
