ABCB8 (ATP binding cassette subfamily B member 8)

Gene

• Entrez ID: 11194
• Gene name: ATP binding cassette subfamily B member 8
• Gene symbol: ABCB8
• Synonyms: EST328128, M-ABC1, MABC1, MITOSUR
• Chromosome: 7
• Chromosome location: 7q36.1
• Summary: This nuclear gene encodes a multi-pass membrane protein that is targeted to the mitochondrial inner membrane. The encoded protein is an ATP-dependent transporter that may mediate the passage of organic and inorganic molecules out of the mitochondria. Loss
