CC -!- FUNCTION: Protein-histidine N-methyltransferase that specifically
CC mediates 3-methylhistidine (tele-methylhistidine) methylation of actin
CC at 'His-73'. Histidine methylation of actin is required for smooth
CC muscle contraction of the laboring uterus during delivery. Does not
CC have protein-lysine N-methyltransferase activity and probably only
CC catalyzes histidine methylation of actin.
CC {ECO:0000250|UniProtKB:Q86TU7}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-histidyl-[protein] + S-adenosyl-L-methionine = H(+) +
CC N(tele)-methyl-L-histidyl-[protein] + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:19369, Rhea:RHEA-COMP:9745, Rhea:RHEA-COMP:11600,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16367, ChEBI:CHEBI:29979,
CC ChEBI:CHEBI:57856, ChEBI:CHEBI:59789; EC=2.1.1.85;
CC Evidence={ECO:0000250|UniProtKB:Q86TU7};
CC -!- SUBUNIT: Interacts with MYOD1. {ECO:0000250|UniProtKB:Q91WC0}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q86TU7}. Nucleus
CC {ECO:0000250|UniProtKB:Q86TU7}. Note=Localizes mainly in the cytoplasm.
CC {ECO:0000250|UniProtKB:Q86TU7}.
CC -!- DOMAIN: The SET domain specifically recognizes and binds actin,
CC suggesting that it does not accommodate substrates diverging from
CC actin. {ECO:0000250|UniProtKB:Q86TU7}.
CC -!- PTM: Phosphorylated by GSK3B, which is required for recognition by the
CC SCF(FBXW7) complex and subsequent degradation.
CC {ECO:0000250|UniProtKB:Q86TU7}.
CC -!- PTM: Ubiquitinated by the SCF(FBXW7) complex following phosphorylation
CC by GSK3B, leading to its degradation by the proteasome.
CC {ECO:0000250|UniProtKB:Q86TU7}.
CC -!- SIMILARITY: Belongs to the class V-like SAM-binding methyltransferase
CC superfamily. SETD3 actin-histidine methyltransferase family.
CC {ECO:0000255|PROSITE-ProRule:PRU00898}.
