Per1

Per1
PFAM accession number:PF04080
Interpro abstract (IPR007217):

PER1 is required for GPI-phospholipase A2 activity and is involved in lipid remodelling of GPI-anchored proteins [ (PUBMED:17021251) ]. PER1 is part of the CREST superfamily [ (PUBMED:21733186) ]. Human PERLD1 is a functional homologue of PER1, and is also known as PGAP3. Mutations in PGAP3 cause hyperphosphatasia with mental retardation syndrome [ (PUBMED:28390064) ].

GO process:GPI anchor biosynthetic process (GO:0006506)
