SETDB1 | Histone-lysine N-methyltransferase SETDB1; Histone methyltransferase that specifically trimethylates 'Lys-9' of histone H3. H3 'Lys-9' trimethylation represents a specific tag for epigenetic transcriptional repression by recruiting HP1 (CBX1, CBX3 and/or CBX5) proteins to methylated histones. Mainly functions in euchromatin regions, thereby playing a central role in the silencing of euchromatic genes. H3 'Lys-9' trimethylation is coordinated with DNA methylation. Required for HUSH- mediated heterochromatin formation and gene silencing. Forms a complex with MBD1 and ATF7IP that represse [...] (1291 aa) | ||||
TRIM4 | E3 ubiquitin-protein ligase TRIM4; E3 ubiquitin-protein ligase. Mediates 'Lys-63'-linked polyubiquitination of the innate immune receptor DDX58, this linkage doesn't lead to proteasomal degradation but seems to enhance IFN induction; Belongs to the TRIM/RBCC family. (500 aa) |
