Protein attributes

Sequence length	199 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Catalyzes three sequential methylation of phosphatidylethanolamine (PE) by AdoMet, thus producing phosphatidylcholine (PC) By similarity.
Catalytic activity	S-adenosyl-L-methionine + phosphatidylethanolamine = S-adenosyl-L-homocysteine + phosphatidyl-N-methylethanolamine.
Enzyme regulation	The first methylation is rate-limiting By similarity.
Subcellular location	Endoplasmic reticulum membrane; Multi-pass membrane protein Potential. Mitochondrion membrane; Multi-pass membrane protein Potential. Note: Found in endoplasmic reticulum where most PEMT activity is generated and in mitochondria By similarity.
Sequence similarities	Belongs to the PEMT/PEM2 methyltransferase family.
