PGK1 (Phosphoglycerate Kinase 1) encodes a crucial glycolytic enzyme that catalyzes the first ATP-generating step in the glycolytic pathway. PGK1 is essential for cellular energy production and has been increasingly implicated in neurodegeneration through metabolic dysfunction, mitochondrial impairment, and bioenergetic crisis in Alzheimer's Disease (AD), Parkinson's Disease (PD), and Amyotrophic Lateral Sclerosis (ALS). The gene is located on chromosome Xq21.1 and encodes a 417-amino acid protein that is highly expressed in brain tissue. [1]

PGK1 is a bilobal enzyme consisting of:
The enzyme undergoes dramatic conformational changes during its catalytic cycle, transitioning from an open (substrate-free) to a closed (substrate-bound) conformation.
PGK1 catalyzes the reversible conversion of 1,3-bisphosphoglycerate (1,3-BPG) to 3-phosphoglycerate (3-PG), generating ATP:
1,3-Bisphosphoglycerate + ADP ↔ 3-Phosphoglycerate + ATP
This is the first substrate-level phosphorylation step in glycolysis, generating ATP independently of oxidative phosphorylation.
PGK1 dysfunction in AD is well-documented:
PGK1 interacts with:
