Identifier: R-HSA-75889

Compartment: cytosol
Dihydroxyacetone phosphate (DHAP) is converted to glycerol-3-phosphate (G3P) by glycerol-3-phosphate dehydrogenase (GPD1) or by glycerol-3-phosphate dehydrogenase-like (GPD1L) enzymes (Ou et al. 2006, Valdivia et al. 2009). The active forms of both enzymes are homodimers. This reaction may be found in white adipose tissues where glycerol-3-kinase activity is not observed in sufficient levels. GPD1/GPD1L reduces dihydroxyacetone phosphate with NADH donating electrons to this reduction.

FAD-linked mitochondrial glycerol 3-phosphate dehydrogenase (GPD2, alias: mGPDH) and its NAD-linked cytosolic isoform (GPD1, alias:cGPDH) constitute glycerol phosphate shuttle. GPD2 catalyzes the unidirectional conversion of glycerol-3-phosphate (G-3-P) to dihydroxyacetone phosphate (DHAP) with concomitant reduction of the enzyme-bound FAD. Impaired activity of GPD2 has been suggested to be one of the primary causes of insulin secretory defects in beta-cells and thus it is a candidate gene for type 2 diabetes.

The set of genes regulated by PPAR-alpha is not fully known in humans, however many examples have been found in mice. Genes directly activated by PPAR-alpha contain peroxisome proliferator receptor elements (PPREs) in their promoters and include:
1) genes involved in fatty acid oxidation and ketogenesis (Acox1, Cyp4a, Acadm, Hmgcs2);
2) genes involved in fatty acid transport (Cd36, , Slc27a1, Fabp1, Cpt1a, Cpt2);
3) genes involved in producing fatty acids and very low density lipoproteins (Me1, Scd1);
4) genes encoding apolipoproteins (Apoa1, Apoa2, Apoa5);
5) genes involved in triglyceride clearance ( Angptl4);
6) genes involved in glycerol metabolism (Gpd1 in mouse);
7) genes involved in glucose metabolism (Pdk4);
8) genes involved in peroxisome proliferation (Pex11a);
9) genes involved in lipid storage (Plin, Adfp).
Many other genes are known to be regulated by PPAR-alpha but whether their regulation is direct or indirect remains to be found. These genes include: ACACA, FAS, SREBP1, FADS1, DGAT1, ABCA1, PLTP, ABCB4, UGT2B4, SULT2A1, Pnpla2, Acsl1, Slc27a4, many Acot genes, and others (reviewed in Rakhshandehroo et al. 2010).
