General annotation (Comments)

Function

Besides it's role as a glycolytic enzyme, mammalian GPI can function as a tumor-secreted cytokine and an angiogenic factor (AMF) that stimulates endothelial cell motility. GPI is also a neurotrophic factor (Neuroleukin) for spinal and sensory neurons By similarity. HAMAP-Rule MF_00473

Catalytic activity

D-glucose 6-phosphate = D-fructose 6-phosphate. HAMAP-Rule MF_00473

Pathway

Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose: step 2/4. HAMAP-Rule MF_00473

Subunit structure

Homodimer in the catalytically active form, monomer in the secreted form. Ref.5

Subcellular location

Cytoplasm. Secreted HAMAP-Rule MF_00473.

Post-translational modification

ISGylated By similarity. HAMAP-Rule MF_00473

Sequence similarities

Belongs to the GPI family.
