What's a GeneRIF?

HRG-1 may represent a novel target for selectively disrupting V-ATPase activity and the metastatic potential of cancer cells.
Title: HRG-1 enhances cancer cell invasive potential and couples glucose metabolism to cytosolic/extracellular pH gradient regulation by the vacuolar-H(+) ATPase.
These results reveal HRG1 as the long-sought heme transporter for heme-iron recycling in macrophages and suggest that genetic variations in HRG1 could be modifiers of human iron metabolism.
Title: HRG1 is essential for heme transport from the phagolysosome of macrophages during erythrophagocytosis.
a model in which heme is translocated across membranes facilitated by conserved amino acids positioned on the exoplasmic, cytoplasmic, and transmembrane regions of HRG-1-related proteins.
Title: Topologically conserved residues direct heme transport in HRG-1-related proteins.
SLC48A1 is a target gene of the BACH1 transcription factor according to ChIP-seq analysis in HEK 293 cells.
Title: The BTB and CNC homology 1 (BACH1) target genes are involved in the oxidative stress response and in control of the cell cycle.
Observational study of gene-disease association, gene-environment interaction, and pharmacogenomic / toxicogenomic. (HuGE Navigator)
Title: Variation at the NFATC2 locus increases the risk of thiazolidinedione-induced edema in the Diabetes REduction Assessment with ramipril and rosiglitazone Medication (DREAM) study.
Observational study of gene-disease association. (HuGE Navigator)
Title: Gene-centric association signals for lipids and apolipoproteins identified via the HumanCVD BeadChip.
HRG-1 regulates V-ATPase activity, which is essential for endosomal acidification, heme binding, and receptor trafficking in mammalian cells.
Title: Heme-binding protein HRG-1 is induced by insulin-like growth factor I and associates with the vacuolar H+-ATPase to control endosomal pH and receptor trafficking.
Human and worm proteins localize together, and bind and transport haem, thus establishing an evolutionarily conserved function for HRG-1.
Title: Haem homeostasis is regulated by the conserved and concerted functions of HRG-1 proteins.

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.
