CC -!- FUNCTION: Polycomb group (PcG) protein. Catalytic subunit of some
CC PcG multiprotein complex, which methylates 'Lys-27' of histone H3,
CC leading to transcriptional repression of the affected target
CC genes. PcG proteins are not required to initiate repression, but
CC to maintain it during later stages of development (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-lysyl-[histone] + S-adenosyl-L-methionine = H(+) +
CC N(6)-methyl-L-lysyl-[histone] + S-adenosyl-L-homocysteine;

CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Widely expressed.
CC {ECO:0000269|PubMed:11950982}.
CC -!- SIMILARITY: Belongs to the class V-like SAM-binding
CC methyltransferase superfamily. Histone-lysine methyltransferase
CC family. EZ subfamily. {ECO:0000255|PROSITE-ProRule:PRU00909}.
