Cholinephosphotransferase 1 (P17898)

Identification
NameCholinephosphotransferase 1
Synonyms
  • Diacylglycerol cholinephosphotransferase 1
  • Sn-1,2-diacylglycerol cholinephosphotransferase
  • CHOPT
Gene NameCPT1
Enzyme Class
Biological Properties
General FunctionInvolved in phosphotransferase activity, for other substituted phosphate groups
Specific FunctionInvolved in protein-dependent process of phospholipid transport to distribute phosphatidyl choline to the lumenal surface. The multiple transmembrane domains and lumenal hydrophilic domains of the cholinephosphotransferase might participate in the transport process
Cellular LocationMicrosome membrane; Multi-pass membrane protein. Endoplasmic reticulum membrane; Multi-pass membrane protein

SMPDB Reactions
Citicoline + 1-O-Hexadecyl-2-O-acetyl-sn-glycerol → Cytidine monophosphate + 2-O-acetyl-1-O-hexadecyl-sn-glycero-3-phosphocholine
1-O-Hexadecyl-2-palmitoyl-sn-glycerol + Citicoline → 1-O-Palmityl-2-palmitoyl-rac-glycero-3-phosphocholine + Cytidine monophosphate
Citicoline + DG(16:0/16:0/0:0) → PC(16:0/16:0) + Cytidine monophosphate + hydron
Citicoline + DG(14:0/14:0/0:0) → Cytidine monophosphate + hydron + PC(14:0/14:0)
Citicoline + DG(10:0/10:0/0:0) → Cytidine monophosphate + hydron + PC(10:0/10:0)
KEGG Reactions
Citicoline + 1,2-dioleoylglycerol ↔ PC(18:1(9Z)/18:1(9Z)) + Cytidine monophosphate
Citicoline + DG(16:0/16:0/0:0) → phosphatidylcholine + Cytidine monophosphate
