Phosphoglucomutase-1 (PGM1) catalyzes the bidirectional interconversion of glucose-1-phosphate (G-1-P) and glucose-6-phosphate (G-6-P).
[1] It regulates carbohydrate metabolism, energy production, and protein N-glycosylation.
[2] PGM1 participates in the biosynthesis of nucleotide sugars required for glycan biosynthesis.
[5] Variation in the PGM1 gene leads to PGM1 deficiency, which is considered an inherited metabolic disorder in humans.
[2][5] PGM1 deficiency causes autosomal recessive diseases such as glycogen storage disease type XIV and congenital disorder of protein N-glycosylation.
[5] Affected patients show multiple disease phenotypes, reflecting the central role of the enzyme in glucose homeostasis. The influence of PGM1 deficiency on protein glycosylation patterns is also widespread.
[1][6] PGM1 acts as a metabolic tumor suppressor.
