Function
function
Catalytic component of the COMPASS (Set1C) complex that specifically mono-, di- and trimethylates histone H3 to form H3K4me1/2/3. Binds RNAs which might negatively affect its histone methyltransferase activity. COMPASS recognizes ubiquitinated H2B on one face of the nucleosome which stimulates the methylation of H3 on the opposing face.

Catalytic activity
- L-lysyl4-[histone H3] + 3 S-adenosyl-L-methionine = 3 H+ + N6,N6,N6-trimethyl-L-lysyl4-[histone H3] + 3 S-adenosyl-L-homocysteine
- N6,N6-dimethyl-L-lysyl4-[histone H3] + S-adenosyl-L-methionine = H+ + N6,N6,N6-trimethyl-L-lysyl4-[histone H3] + S-adenosyl-L-homocysteine
- N6-methyl-L-lysyl4-[histone H3] + S-adenosyl-L-methionine = H+ + N6,N6-dimethyl-L-lysyl4-[histone H3] + S-adenosyl-L-homocysteine
