General annotation (Comments)

Function

Catalyzes the post-translational methylation of isoprenylated C-terminal cysteine residues. Carboxyl methylation is a reversible and potentially regulated step in the post-translational modification of prenylated proteins By similarity.

Catalytic activity

S-adenosyl-L-methionine + protein C-terminal S-farnesyl-L-cysteine = S-adenosyl-L-homocysteine + protein C-terminal S-farnesyl-L-cysteine methyl ester.

Cofactor

Divalent cations. Probably zinc By similarity.

Subcellular location

Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity.

Sequence similarities

Belongs to the class VI-like SAM-binding methyltransferase superfamily. Isoprenylcysteine carboxyl methyltransferase family.

Sequence caution

The sequence BAF15691.1 differs from that shown. Reason: Erroneous gene model prediction.
