 -!- FUNCTION: Mediates the octanoylation of ghrelin at 'Ser-3'. Can
     use a variety of fatty acids as substrates including octanoic
     acid, decanoic acid and tetradecanoic acid.
     {ECO:0000269|PubMed:18443287}.
 -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
     {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}.
 -!- ALTERNATIVE PRODUCTS:
     Event=Alternative splicing; Named isoforms=2;
     Name=1;
       IsoId=Q96T53-1; Sequence=Displayed;
     Name=2;
       IsoId=Q96T53-2; Sequence=VSP_032958, VSP_032959;
       Note=No experimental confirmation available.;
 -!- TISSUE SPECIFICITY: Expressed predominantly in stomach with
     moderate levels in pancreas and relatively low levels in most
     other tissues. {ECO:0000269|PubMed:18443287}.
 -!- SIMILARITY: Belongs to the membrane-bound acyltransferase family.
     {ECO:0000305}.
