Histone-lysine N-methyltransferase KMT5C (KMT5C)

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 organization of constitutive heterochromatin in these regions. KMT5C is targeted to histone H3 via its interaction with RB1 family proteins (RB1, RBL1 and RBL2) (By similarity).
