    Background

    PGK1 (phosphoglycerate kinase) is an essential enzyme in the glycolysis pathway (1). It catalyzes the reversible phospho-transfer reaction from 1,3-diphosphoglycerate to ADP to form ATP and 3-phosphoglycerate. The expression of PGK1 is upregulated in many cancer types and plays an important role in cancer cell proliferation and metastasis (2-5). PGK1 can also function as a protein kinase. ERK can phosphorylate PGK1 at Ser203. This phosphorylation changes PGK1 conformation and leads to its translocation from cytoplasm to mitochondria. There it interacts and phosphorylates PDHK1 (pyruvate dehydrogenase kinase isomerase 1), which leads to PDHK1 inhibition, blocks pyruvate to coenzyme A conversion, and promotes cytosolic lactate concentration (6). Acetylated PGK1 can phosphorylate Beclin1 to induce autophagy (7). PGK1 is activated by autophosphorylation at Tyr324. PTEN can dephosphorylate PGK1 at this site to downregulate its activity. In cancer cells, loss of PTEN enhances PGK1 activity and promotes glycolysis and tumor growth (8).
