Background: TIGAR/C12orf5

Fructose-2,6-bisphosphatase TIGAR (TIGAR), also known as TP53-induced glycolysis and apoptosis regulator, is a highly conserved, ubiquitously expressed enzyme from the phosphoglycerate mutase family that hydrolyzes fructose-2,6-bisphosphate, a key regulator of cellular metabolism that activates glycolysis and inhibits gluconeogenesis (1). Consequently, TIGAR acts as a negative regulator of glycolysis and its activity results in pentose phosphate pathway activation and NADPH production. Human TIGAR is a 270 amino acid monomeric protein with a histidine phosphatase fold containing a phosphate coordinated to a catalytic histidine in the active site (2). It is located both in the cytoplasm and in organelles where its function may vary (1); translocation of TIGAR to the nucleus promotes cell survival during chemotherapy and hypoxia (3) while transportation to the mitochondria under hypoxia can enhance HK2 activity and maintain cell survival (4) or interact with ATP5A1 to reduce oxidative stress (1). TIGAR is a target gene of p53 through binding sequences in the promoter region (5) and may promote cancer metastasis through both enzymatic function and through interactions that allow it to mediate signaling pathways that inhibit autophagy and apoptosis (6, 7). TIGAR is highly expressed in some tumors (1) and may be a potential therapeutic target for cancers (6-8), cardiovascular disease (9), and neurological diseases (10-13).
