Protein: Histone-lysine N-methyltransferase SETDB2 (EC 2.1.1.366) (SET domain bifurcated 2) (Q06ZW3)
Organism: Danio rerio (Zebrafish) (Brachydanio rerio)
Function: Histone methyltransferase involved in left-right axis specification in early development and mitosis. Specifically trimethylates 'Lys-9' of histone H3 (H3K9me3). H3K9me3 represents a specific tag for epigenetic transcriptional repression by recruiting HP1 (CBX1, CBX3 and/or CBX5) proteins to methylated histones. Contributes to H3K9me3 in both the interspersed repetitive elements and centromere-associated repeats. Plays a role in chromosome condensation and segregation during mitosis. During early development, required to specify the left-right axis by repressing expression of FGF8, leading to negatively regulate the dorsal organizer formation.
Subcellular location: Nucleus {ECO:0000250}. Chromosome {ECO:0000250}.
