TTD, tandem tudor domain within UHRF1 preferentially binds H3 histone tails trimethylated at Lys-9. It specifically recognises H3 tail peptides with the heterochromatin-associated modification state of trimethylated lysine 9 and unmodified lysine 4 (H3K4me0/K9me3). This domain is found in eukaryotes and is found in association with Pfam:PF00097, Pfam:PF02182, Pfam:PF00628, Pfam:PF00240.	Domain
A	PF00628	PHD-finger (PHD)	PHD-finger	PHD folds into an interleaved type of Zn-finger chelating 2 Zn ions in a similar manner to that of the RING and FYVE domains [2]. Several PHD fingers have been identified as binding modules of methylated histone H3 [3].	Domain
