Protein
Histone-lysine N-methyltransferase EZ2
Gene
EZ2, MEZ2
Organism
Zea mays (Maize)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at transcript leveli

Functioni

Polycomb group (PcG) protein. Catalytic subunit of some PcG multiprotein complex, which methylates 'Lys-27' of histone H3, leading to transcriptional repression of the affected target genes. PcG proteins are not required to initiate repression, but to maintain it during later stages of development By similarity.

Catalytic activityi

S-adenosyl-L-methionine + L-lysine-[histone] = S-adenosyl-L-homocysteine + N(6)-methyl-L-lysine-[histone].
