What's a GeneRIF?

physiological evidence demonstrates the existence of in vivo synthesis of trans11,cis13-CLA from dietary trans-vaccenic acid in rodents; and establishes the FADS3 enzyme as a reliable mammalian trans-vaccenate Delta13-desaturase in vivo.
Title: Conversion of dietary trans-vaccenic acid to trans11,cis13-conjugated linoleic acid in the rat lactating mammary gland by Fatty Acid Desaturase 3-catalyzed methyl-end Δ13-desaturation.
FADS3 was secreted specifically by hepatocytes in the extracellular matrix where it was located on fibronectin-containing fibers.The 51 kDa FADS3 is secreted in the extracellular matrix of hepatocytes and blood.
Title: The 51 kDa FADS3 is secreted in the ECM of hepatocytes and blood in rat.
FADS3 is the first "methyl-end" fatty acid desaturase functionally characterized in mammals
Title: Trans-vaccenate is Δ13-desaturated by FADS3 in rodents.
FADS3 does exist under multiple protein isoforms depending on the mammalian tissues.
Title: The fatty acid desaturase 3 gene encodes for different FADS3 protein isoforms in mammalian tissues.

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.
