Summaries for FADS3 Gene

Entrez Gene Summary for FADS3 Gene

  • The protein encoded by this gene is a member of the fatty acid desaturase (FADS) gene family. Desaturase enzymes regulate unsaturation of fatty acids through the introduction of double bonds between defined carbons of the fatty acyl chain. FADS family members are considered fusion products composed of an N-terminal cytochrome b5-like domain and a C-terminal multiple membrane-spanning desaturase portion, both of which are characterized by conserved histidine motifs. This gene is clustered with family members FADS1 and FADS2 at 11q12-q13.1; this cluster is thought to have arisen evolutionarily from gene duplication based on its similar exon/intron organization.

GeneCards Summary for FADS3 Gene

FADS3 (Fatty Acid Desaturase 3) is a Protein Coding gene. GO annotations related to this gene include iron ion binding and oxidoreductase activity, acting on paired donors, with oxidation of a pair of donors resulting in the reduction of molecular oxygen to two molecules of water. An important paralog of this gene is FADS1.
