PEX3 (peroxisomal biogenesis factor 3)

Gene

• Entrez ID: 8504
• Gene name: Peroxisomal biogenesis factor 3
• Gene symbol: PEX3
• Synonyms: PBD10A, PBD10B, TRG18
• Chromosome: 6
• Chromosome location: 6q24.2
• Summary: The product of this gene is involved in peroxisome biosynthesis and integrity. It assembles membrane vesicles before the matrix proteins are translocated. Peroxins (PEXs) are proteins that are essential for the assembly of functional peroxisomes. The pero
