Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0001803
UniProt IDQ53F39
Primary gene name(s)MPPE1
Synonym gene name(s)PGAP5
Protein nameMetallophosphoesterase 1
Protein functionMetallophosphoesterase required for transport of GPI-anchor proteins from the endoplasmic reticulum to the Golgi. Acts in lipid remodeling steps of GPI-anchor maturation by mediating the removal of a side-chain ethanolamine-phosphate, EtNP from the second Man, Man2 of the GPI intermediate, an essential step for efficient transport of GPI-anchor proteins. {ECO:0000269|PubMed:19837036}.
Subcellular locationEndoplasmic reticulum-Golgi intermediate compartment membrane {ECO:0000269|PubMed:19837036};
Multi-pass membrane protein {ECO:0000269|PubMed:19837036}. Golgi apparatus, cis-Golgi network membrane {ECO:0000269|PubMed:19837036};
Multi-pass membrane protein {ECO:0000269|PubMed:19837036}. Note=Also localizes to endoplasmic reticulum exit site.
