Essential role of Elovl4 in very long chain fatty acid synthesis, skin permeability barrier function, and neonatal survival
Mutations in the gene ELOVL4 have been shown to cause stargardt-like macular dystrophy. ELOVL4 is part of a family of fatty acid elongases and is yet to have a specific elongase activity assigned to it. We generated Elovl4 Y270X mutant mice and characterized the homozygous mutant as well as homozygous Elovl4 knockout mice in order to better understand the function or role of Elovl4. We found th...
متن کاملRole of ELOVL4 and very long-chain polyunsaturated fatty acids in mouse models of Stargardt type 3 retinal degeneration.
Stargardt type 3 (STGD3) disease is a juvenile macular dystrophy caused by mutations in the ELOVL4 (Elongation of very long chain fatty acids 4) gene. Its protein product, ELOVL4, is an elongase required for the biosynthesis of very long-chain polyunsaturated fatty acids (VLC-PUFAs). It is unclear whether photoreceptor degeneration in STGD3 is caused by loss of VLC-PUFAs or by mutated ELOVL4 pr...
متن کاملRole of Stargardt-3 macular dystrophy protein (ELOVL4) in the biosynthesis of very long chain fatty acids.
Stargardt-like macular dystrophy (STGD3) is a dominantly inherited juvenile macular degeneration that eventually leads to loss of vision. Three independent mutations causing STGD3 have been identified in exon six of a gene named Elongation of very long chain fatty acids 4 (ELOVL4). The ELOVL4 protein was predicted to be involved in fatty acid elongation, although evidence for this and the speci...
متن کاملFatty acid binding protein. Role in esterification of absorbed long chain fatty acid in rat intestine.
Fatty acid binding protein (FABP) is a protein of 12,000 mol wt found in cytosol of intestinal mucosa and other tissues, which exhibits high affinity for long chain fatty acids. It has been suggested that FABP (which may comprise a group of closely related proteins of 12,000 mol wt) participates in cellular fatty acid transport and metabolism. Although earlier findings were consistent with this...
متن کاملPlasmalogens participate in very-long-chain fatty acid-induced pathology.
Peroxisomes are organelles responsible for multiple metabolic pathways including, the biosynthesis of plasmalogens, a class of phospholipids, and the beta-oxidation of very-long-chain fatty acids (VLCFA). Lack of peroxisomes or dysfunction in any of their normal functions is the cellular basis for human peroxisomal disorders. Here we used mouse models to understand and define the biochemical an...
