ICMTB

Gene
ICMTB
Protein
Protein-S-isoprenylcysteine O-methyltransferase B
Organism
Arabidopsis thaliana
Length
197 amino acids
Function
Catalyzes the post-translational methylation of isoprenylated C-terminal cysteine residues, resulting in the modulation of the function of prenylated proteins. Involved in negative regulation of abscisic acid signaling. Carboxyl methylation is a reversible and potentially regulated step in the post-translational modification of prenylated proteins.
Similarity
Belongs to the class VI-like SAM-binding methyltransferase superfamily. Isoprenylcysteine carboxyl methyltransferase family.
Mass
