CC -!- FUNCTION: Protein-serine O-palmitoleoyltransferase that acts as a key
CC regulator of the Wnt signaling pathway by mediating the attachment of
CC palmitoleate, a 16-carbon monounsaturated fatty acid (C16:1), to Wnt
CC proteins. Serine palmitoleylation of Wnt proteins is required for
CC efficient binding to frizzled receptors (By similarity). Also
CC facilitates the glycosylation of Wnt family members, including wg and
CC Wnt5. The cotranslational disulfide bond formation of wg competes with
CC the N-glycosylation. Porc stimulates the post-translational N-
CC glycosylation by anchoring wg at the ER membrane, probably through
CC acylation (PubMed:11821428, PubMed:15166250, PubMed:22108505,
CC PubMed:8985181). {ECO:0000250|UniProtKB:Q9JJJ7,

CC ECO:0000269|PubMed:22108505, ECO:0000269|PubMed:8985181}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(9Z)-hexadecenoyl-CoA + [Wnt protein]-L-serine = [Wnt
CC protein]-O-(9Z)-hexadecenoyl-L-serine + CoA; Xref=Rhea:RHEA:45336,

CC EC=2.3.1.250; Evidence={ECO:0000250|UniProtKB:Q9JJJ7};
CC -!- SUBUNIT: Interacts with wg and Wnt5. {ECO:0000269|PubMed:11821428}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000269|PubMed:11821428, ECO:0000269|PubMed:8985181}; Multi-pass
CC membrane protein {ECO:0000269|PubMed:11821428,
CC ECO:0000269|PubMed:8985181}.
CC -!- DEVELOPMENTAL STAGE: Expressed both maternally and zygotically.
CC {ECO:0000269|PubMed:8985181}.
CC -!- SIMILARITY: Belongs to the membrane-bound acyltransferase family.
CC Porcupine subfamily. {ECO:0000305}.
CC -!- CAUTION: Was initially thought to mediate palmitoylation of Wnt
CC proteins. It was later shown that it instead acts as a serine O-
CC palmitoleoyltransferase that mediates the attachment of palmitoleate, a
CC 16-carbon monounsaturated fatty acid (C16:1), to Wnt proteins.
CC {ECO:0000305}.
