CC -!- FUNCTION: Protein-lysine N-methyltransferase that methylates both
CC histones and non-histone proteins, including p53/TP53 and RB1.
CC Specifically trimethylates histone H3 'Lys-4' (H3K4me3) in vivo. The
CC activity requires interaction with HSP90alpha. Shows even higher
CC methyltransferase activity on p53/TP53. Monomethylates 'Lys-370' of
CC p53/TP53, leading to decreased DNA-binding activity and subsequent
CC transcriptional regulation activity of p53/TP53. Monomethylates RB1 at
CC 'Lys-860'. {ECO:0000250|UniProtKB:Q9NRG4}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-lysyl(4)-[histone H3] + 3 S-adenosyl-L-methionine = 3 H(+) +
CC N(6),N(6),N(6)-trimethyl-L-lysyl(4)-[histone H3] + 3 S-adenosyl-L-
CC homocysteine; Xref=Rhea:RHEA:60260, Rhea:RHEA-COMP:15537, Rhea:RHEA-

CC ChEBI:CHEBI:59789, ChEBI:CHEBI:61961; EC=2.1.1.354;
CC Evidence={ECO:0000250|UniProtKB:Q9NRG4};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-lysyl-[protein] + S-adenosyl-L-methionine = H(+) + N(6)-
CC methyl-L-lysyl-[protein] + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:51736, Rhea:RHEA-COMP:9752, Rhea:RHEA-COMP:13053,

CC ChEBI:CHEBI:59789, ChEBI:CHEBI:61929;
CC Evidence={ECO:0000250|UniProtKB:Q9NRG4};
CC -!- SUBUNIT: Interacts with RNA polymerase II and HELZ. Interacts with
CC SIN3A and HDAC1. Interacts (via MYND-type zinc finger) with EPB41L3.
CC Interacts (via SET domain) with p53/TP53. Interacts with RB1 and
CC HSP90AA1 (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol {ECO:0000250}. Nucleus
CC {ECO:0000250}.
CC -!- DEVELOPMENTAL STAGE: During fetal muscle development, expression
CC increases from 33 to 90 dpc. {ECO:0000269|PubMed:19133938}.
CC -!- SIMILARITY: Belongs to the class V-like SAM-binding methyltransferase
CC superfamily. {ECO:0000255|PROSITE-ProRule:PRU00190}.
