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. Probably forms a complex with MBD1 and ATF7IP that represses transcription and couples DNA methylation and histone 'Lys-9' [...] (1308 aa) | ||||
Mtmr2 | Myotubularin-related protein 2; Phosphatase that acts on lipids with a phosphoinositol headgroup. Has phosphatase activity towards pho sphatidylinositol 3-phosphate and phosphatidylinositol 3,5- bisphosphate. Binds phosphatidylinositol 4-phosphate, phosphatidylinositol 5-phosphate, phosphatidylinositol 3,5-bisphosphate and phosphatidylinositol 3,4,5- trisphosphate. Stabilizes SBF2/MTMR13 at the membranes. Specifically in peripheral nerves, stabilizes SBF2/MTMR13 protein. Belongs to the protein-tyrosine phosphatase family. Non- receptor class myotubularin subfamily. (643 aa) |
