The structure of the Suv4-20h2 ternary complex with histone H4

Template:ABSTRACT PUBMED 24049080

Function

[SV422_MOUSE] Histone methyltransferase that specifically trimethylates 'Lys-20' of histone H4. H4 'Lys-20' trimethylation represents a specific tag for epigenetic transcriptional repression. 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).[1]

About this Structure

4au7 is a 3 chain structure with sequence from Lk3 transgenic mice. Full crystallographic information is available from OCA.
