Recombinant Human SUV420H2 Protein (His & GST Tag)

Histone-lysine N-methyltransferase SUV420H2, also known as Suppressor of variegation 4-20 homolog 2, Su (var) 4-20 homolog 2, Lysine N-methyltransferase 5C, SUV420H2 and KMT5C, is nucleus protein which belongs to thehistone-lysine methyltransferase family and Suvar4-20 subfamily. SUV420H2 is a histone methyltransferase that specifically trimethylates 'Lys-20' of histone H4. H4 'Lys-20' trimethylation represents a specific tag for epigenetic transcriptional repression. SUV420H2 mainly functions in pericentric heterochromatin regions, thereby playing a central role in the establishment of constitutive heterochromatin in these regions. SUV420H1 is targeted to histone H3 via its interaction with RB1 family proteins (RB1, RBL1 and RBL2) . FRAP experiments reveal that SUV420H2 is strongly associated to pericentric heterochromatin. The fraction of SUV420H2 captured and characterized by TAP/MS is a soluble fraction which may be in a stable association with HP1. SUV420H2 may be recruited to heterochromatin in association with HP1, and stably maintained at its heterochromatin sites in an HP1-independent fashion.

Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
