SUV420H2 Protein, Human, Recombinant (His & GST)

Histone-lysine N-methyltransferase SUV42H2, also known as Suppressor of variegation 4-2 homolog 2, Su (var) 4-2 homolog 2, Lysine N-methyltransferase 5C, SUV42H2 and KMT5C, is nucleus protein that belongs to the histone-lysine methyltransferase family and Suvar4-2 subfamily. SUV42H2 is a histone methyltransferase that specifically trimethylates 'Lys-2' of histone H4. H4 'Lys-2' trimethylation represents a specific tag for epigenetic transcriptional repression. SUV42H2 mainly functions in pericentric heterochromatin regions, thereby playing a central role in the establishment of constitutive heterochromatin in these regions. SUV42H1 is targeted to histone H3 via its interaction with RB1 family proteins (RB1, RBL1 and RBL2) . FRAP experiments reveal that SUV42H2 is strongly associated with pericentric heterochromatin. The fraction of SUV42H2 captured and characterized by TAP/MS is a soluble fraction which may be in a stable association with HP1. SUV42H2 may be recruited to heterochromatin in association with HP1, and stably maintained at its heterochromatin sites in an HP1-independent fashion.
