Protein attributes

Sequence length	1956 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Histone methyltransferase that specifically methylates 'Lys-4' of histone H3, when part of the SET1 histone methyltransferase (HMT) complex, but not if the neighboring 'Lys-9' residue is already methylated. H3 'Lys-4' methylation represents a specific tag for epigenetic transcriptional activation By similarity.
Catalytic activity	S-adenosyl-L-methionine + histone L-lysine = S-adenosyl-L-homocysteine + histone N(6)-methyl-L-lysine.
Subcellular location	Nucleus speckle By similarity.
Sequence similarities	Contains 1 post-SET domain. Contains 1 RRM (RNA recognition motif) domain. Contains 1 SET domain.
