Summary: Enables Wnt-protein binding activity and palmitoleoyltransferase activity. Involved in Wnt signaling pathway; protein palmitoleylation; and regulation of postsynaptic membrane neurotransmitter receptor levels. Acts upstream of or within glycoprotein metabolic process. Located in endoplasmic reticulum membrane. Part of AMPA glutamate receptor complex. Is active in glutamatergic synapse. Is expressed in several structures, including anterior visceral endoderm; genitourinary system; nervous system; primitive streak; and sensory organ. Used to study focal dermal hypoplasia. Human ortholog(s) of this gene implicated in focal dermal hypoplasia. Orthologous to human PORCN (porcupine O-acyltransferase). [provided by Alliance of Genome Resources, Nov 2024]

Title: Porcupine-dependent Wnt activity within the uterine epithelium is essential for fertility.
Data suggest that PORCN exhibits substrate specificity that includes a Wnt3a peptide fragment (residues 199-219, with disulfide bonds); recombinant PORCN containing a point mutation (R228C) associated with focal dermal hypoplasia exhibits impaired acylation activity toward Wnt3a peptide fragment.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Status: VALIDATED

Description

Transcript Variant: This variant (f) uses alternate splice sites at two internal exons compared to variant a. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
