What's a GeneRIF?

Early stages of lineage fate potential require glutamine anaplerotic functions and an intact Pentose phosphate pathway, which are, in part, regulated by BLVRB activity. In principle, BLVRB inhibition represents an alternative strategy for modulating cellular glutamine utilization with consequences for cancer and hematopoietic metabolism.
Title: Heme degradation enzyme biliverdin IXβ reductase is required for stem cell glutamine metabolism.
These results provide promising chemical scaffolds for the development of enhanced BLVRB inhibitors and identify chemical probes to better dissect the role of biliverdins, alternative substrates, and BLVRB function in physiologically relevant cellular contexts.
Title: <i>In silico</i> and crystallographic studies identify key structural features of biliverdin IXβ reductase inhibitors having nanomolar potency.
These data define the first physiologically relevant function of BLVRB and implicate its activity and/or heme-regulated BV tetrapyrrole(s) in a unique redox-regulated bioenergetic pathway.
Title: BLVRB redox mutation defines heme degradation in a metabolic pathway of enhanced thrombopoiesis in humans.
miR-127-5p suppressed NF-kappaB activity by directly targeting BLVRB in hepatocellular carcinoma cells.
Title: MicroRNA-127-5p targets the biliverdin reductase B/nuclear factor-κB pathway to suppress cell growth in hepatocellular carcinoma cells.
Data suggest that isoenzymes BVRA and BVRB play different roles in energy metabolism and in pathogenesis of abdominal obesity and hypertriglyceridemia. [REVIEW]
Title: Biliverdin reductase isozymes in metabolism.
quantum mechanics/molecular mechanics potential energy surfaces show that the lowest energy pathway proceeds with a positively charged pyrrole intermediate via two transition states

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.
