CC   -!- FUNCTION: Golgi-resident glycosylphosphatidylinositol (GPI)-N-
CC       acetylgalactosamine transferase involved in the lipid remodeling steps
CC       of GPI-anchor maturation. Lipid remodeling steps consist in the
CC       generation of 2 saturated fatty chains at the sn-2 position of GPI-
CC       anchors proteins. Required for the initial step of GPI-GalNAc
CC       biosynthesis, transfers GalNAc to GPI in the Golgi after fatty acid
CC       remodeling by PGAP2. {ECO:0000250|UniProtKB:Q9BRR3}.
CC   -!- SUBCELLULAR LOCATION: Golgi apparatus membrane
CC       {ECO:0000250|UniProtKB:Q9BRR3}; Multi-pass membrane protein
CC       {ECO:0000250|UniProtKB:Q9BRR3}.
CC   -!- DOMAIN: Contains three transmembrane domains, including a tandem
CC       transmembrane domain insertion into its glycosyltransferase-A fold.
CC       Transmembrane domain 1 functions as a signal for Golgi targeting.
CC       {ECO:0000250|UniProtKB:Q9BRR3}.
CC   -!- DOMAIN: The conserved DXD motif is involved in enzyme activity.
CC       {ECO:0000250|UniProtKB:Q9BRR3}.
CC   -!- SIMILARITY: Belongs to the PGAP4 family. {ECO:0000305}.
