Icmt - isoprenylcysteine carboxyl methyltransferase

Enables protein C-terminal S-isoprenylcysteine carboxyl O-methyltransferase activity. Involved in C-terminal protein methylation; S-adenosylhomocysteine metabolic process; and S-adenosylmethioninamine metabolic process. Located in membrane. Orthologous to human ICMT (isoprenylcysteine carboxyl methyltransferase). [provided by Alliance of Genome Resources, Apr 2022]
