What's a GeneRIF?

These results indicate that ABCB8 is essential for normal cardiac function, maintenance of mitochondrial iron homeostasis and maturation of cytosolic Fe/S proteins.
Title: Disruption of ATP-binding cassette B8 in mice leads to cardiomyopathy through a decrease in mitochondrial iron export.
In the testis, rat abcb8 was expressed both in the somatic Sertoli cells and peritubular cells and in the germline (spermatogonia and pachytene spermatocytes).
Title: Molecular cloning of several rat ABC transporters including a new ABC transporter, Abcb8, and their expression in rat testis.

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.
