About ABCB8

Cytogenetic location: 7q36.1 Genomic coordinates (GRCh38): 7:151,028,450-151,047,782 (from NCBI)

This gene has 22 transcripts (splice variants), 201 orthologues and 10 paralogues. Ubiquitous expression in testis (RPKM 5.6), endometrium (RPKM 5.4) and 25 other tissues.

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 of function of the related gene in mouse results in a disruption of iron homeostasis between the mitochondria and cytosol. Alternative splicing results in multiple transcript variants.
