PIG-F

PIG-F
PFAM accession number:PF06699
Interpro abstract (IPR009580):

Glycosylphosphatidylinositol anchor biosynthesis protein Pig-F is involved in glycosylphosphatidylinositol (GPI) anchor biosynthesis [ (PUBMED:10781593) (PUBMED:11995915) (PUBMED:12655644) ]. This family also includes the Pif-F homologue GPI11 (glycosylphosphatidylinositol anchor biosynthesis protein 11) [ (PUBMED:10793139) ]. It is involved in the ethanolamine-phosphate transfer-step of GPI biosynthesis [ (PUBMED:25074286) ].

GO process:GPI anchor biosynthetic process (GO:0006506)
GO component:endoplasmic reticulum membrane (GO:0005789)
