UniProtKB - G3V6U9 (SETD3_RAT)
Actin-histidine N-methyltransferase
Setd3
Functioni
Protein-histidine N-methyltransferase that specifically mediates 3-methylhistidine (tele-methylhistidine) methylation of actin at 'His-73' (PubMed:30526847).
Histidine methylation of actin is required for smooth muscle contraction of the laboring uterus during delivery (By similarity).
Does not have protein-lysine N-methyltransferase activity and probably only catalyzes histidine methylation of actin (By similarity).
By similarity1 PublicationCatalytic activityi
- L-histidyl-[protein] + S-adenosyl-L-methionine = H+ + Nτ-methyl-L-histidyl-[protein] + S-adenosyl-L-homocysteine1 PublicationEC:2.1.1.851 PublicationThis reaction proceeds in the forward1 Publication direction.
Kineticsi
- KM=2.996 µM for beta-actin1 Publication
- KM=0.109 µM for S-adenosyl-L-methionine1 Publication
