{{Infobox_gene}}

Peroxisome assembly protein 12 is a protein that in humans is encoded by the PEX12 gene.{{cite journal | vauthors = Chang CC, Lee WH, Moser H, Valle D, Gould SJ | title = Isolation of the human PEX12 gene, mutated in group 3 of the peroxisome biogenesis disorders | journal = Nat Genet | volume = 15 | issue = 4 | pages = 385–8 |date=April 1997 | pmid = 9090384 | doi = 10.1038/ng0497-385 | s2cid = 20825062 }}

Function

PEX12 is needed for protein import into peroxisomes.{{cite journal | vauthors = Okumoto K, Shimozawa N, Kawai A, Tamura S, Tsukamoto T, Osumi T, Moser H, Wanders RJ, Suzuki Y, Kondo N, Fujiki Y | title = PEX12, the pathogenic gene of group III Zellweger syndrome: cDNA cloning by functional complementation on a CHO cell mutant, patient analysis, and characterization of PEX12p | journal = Mol.

Peroxins (PEXs) are proteins that are essential for the assembly of functional peroxisomes.

Clinical significance

The peroxisome biogenesis disorders (PBDs; MIM 601539) are a group of genetically heterogeneous diseases that are usually lethal in early infancy. Although the clinical features of PBD patients vary, cells from all PBD patients exhibit a defect in the import of one or more classes of peroxisomal matrix proteins into the organelle. This cellular phenotype is shared by yeast 'pex' mutants, and human orthologs of yeast PEX genes defective in some PBD complementation groups (CGs).{{cite web | title = Entrez Gene: PEX12 peroxisomal biogenesis factor 12| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=5193}}
