Background: PGM1

Phosphoglucomutase-1 (PGM1) has a central role in metabolism as it mediates the switch between glycolysis and gluconeogenesis by catalyzing the interconversion of glucose 1-phosphate and glucose 6-phosphate within the nucleotide sugar, galactose, and pentose phosphate pathways and is involved in protein N-glycosylation (1). It is a member of the phosphohexose mutase family and is ubiquitously expressed in tissues and organs (1,2). PGM1 is a cytosolic, magnesium-dependent monomer with four domains that form an overall heart shape (1,2). The active site is located in a large central cleft in the middle of the four domains that contain a catalytic phosphoserine that participates in phosphoryl transfer, a metal binding loop, a sugar-binding loop, and a phosphate-binding site (2).  Deficiency in PGM1 activity has been identified to cause glycogen storage disorder GSD XIV and is also a rare genetic disorder congenital disorder of glycosylation (CDG) called PGM1-CDG or CDG1T (3-6) with affected individuals showing multiple disease phenotypes including cardiomyopathy, muscular weakness, and hepatopathy (4,6,7). Some, but not all, clinical symptoms can be improved with oral D-galactose treatment (4,7,8). In addition, PGM1 is down-regulated in cancers such as hepatocellular carcinoma (HCC) and colorectal cancer (CRC) and up-regulated cancers such as lung and gastric cancer where it has been linked to lower survival in all cases making PGM1 a potential biomarker in several cancers (9-12). Galactose supplementation was not corrective in HCC suggesting PGM1's role in regulation of glycogen synthesis and glucose regulation is critical in promotion of tumor cell proliferation and growth (9,10,12,13). Given the key role PGM1 plays in metabolism in cancer and disease there is interest in PGM1 as a therapeutic target (10-12).
