  • 1 - PEMT Antibody (N-term) AP1025a
    Western blot analysis of lysates from CEM, rat L6 cell line and human liver tissue lysate(from left to right), using PEMT Antibody (N-term)(Cat. #AP1025a). AP1025a was diluted at 1:1000 at each lane. A goat anti-rabbit IgG H&L(HRP) at 1:10000 dilution was used as the secondary antibody. Lysates at 35ug per lane.
  • 1 - PEMT Antibody (N-term) AP1025a
    Western blot analysis of anti-PEMT Antibody (N-term) Pab (Cat.#AP1025a) in mouse kidney tissue lysates (35ug/lane). PEMT(arrow) was detected using the purified Pab.
  • 14 - PEMT Antibody (N-term) AP1025a
    Formalin-fixed and paraffin-embedded human hepatocarcinoma tissue reacted with PEMT antibody (N-term) (Cat.#AP1025a), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.

Protein Information
Name PEMT {ECO:0000255|HAMAP-Rule:MF_03216}
Synonyms PEMPT, PNMT
Function Catalyzes the three sequential steps of the methylation pathway for the biosynthesis of phosphatidylcholine, a critical and essential component for membrane structure (PubMed:12431977, PubMed:15927961). Uses S-adenosylmethionine (S-adenosyl-L-methionine, SAM or AdoMet) as the methyl group donor for the methylation of phosphatidylethanolamine (1,2-diacyl-sn-glycero-3-phosphoethanolamine, PE) to phosphatidylmonomethylethanolamine (1,2-diacyl-sn-glycero-3- phospho-N-methylethanolamine, PMME), PMME to phosphatidyldimethylethanolamine (1,2-diacyl-sn-glycero-3-phospho-N,N- dimethylethanolamine, PDME), and PDME to phosphatidylcholine (1,2- diacyl-sn-glycero-3-phosphocholine, PC), producing S-adenosyl-L- homocysteine in each step (PubMed:12431977, PubMed:15927961). Responsible for approximately 30% of hepatic PC with the CDP-choline pathway accounting for the other 70% (Probable).
Cellular Location Endoplasmic reticulum. Note=localized in the endoplasmic reticulum (ER) of the liver and in a lipid metabolism-rich region of the ER known as mitochondria-associated membranes (PubMed:15927961) Adopts a topography within the ER membrane that positions both termini in the cytosol (PubMed:12431977). [Isoform 2]: Endoplasmic reticulum membrane; Multi-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_03216}
Tissue Location Primarily expressed in liver (at protein level).

BACKGROUND

This gene encodes an enzyme which converts phosphatidylethanolamine to phosphatidylcholine by sequential methylation in the liver. The protein localizes to the endoplasmic reticulum and mitochondria-associated membranes. The gene is within the Smith-Magenis syndrome region on chromosome 17. Alternate splicing of this gene results in three transcript variants encoding two different isoforms.
