This protein is involved in step 1 of the subpathway that synthesizes phosphatidylcholine from phosphocholine.By similarity
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Choline-phosphate cytidylyltransferase B (PCYT1B), Choline-phosphate cytidylyltransferase A (PCYT1A)
  2. Choline/ethanolaminephosphotransferase 1 (CEPT1), Cholinephosphotransferase 1 (CHPT1)
This subpathway is part of the pathway phosphatidylcholine biosynthesis, which is itself part of Phospholipid metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes phosphatidylcholine from phosphocholine, the pathway phosphatidylcholine biosynthesis and in Phospholipid metabolism.

<p>This subsection of the ‘Entry information’ section provides one or more accession number(s). These are stable identifiers and should be used to cite UniProtKB entries.
