What's a GeneRIF?

Data suggest that a major portion of intracellular glucose in cardiac myocytes is apportioned for ancillary biosynthetic reactions; PFKFB1 coordinates activities of pentose phosphate, hexosamine biosynthetic, and fatty acid/glycerolipid synthesis pathways by directly modulating glycolytic intermediate entry into auxiliary glucose metabolism pathways and by indirectly regulating mitochondrial cataplerosis.

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.
