[[https://www.uniprot.org/uniprot/G6PI_RABIT G6PI_RABIT]] 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).

== Publication Abstract from PubMed ==
Phosphoglucose isomerase (PGI) is a housekeeping enzyme of metabolism that catalyses the interconversion of glucose 6-phosphate and fructose 6-phosphate, with roles in the glycolytic and gluconeogenic pathways. PGI is also a multifunctional protein that manifests the properties of a cytokine in a wide array of cellular processes, including the production of immunoglobulin by B cells and tumour-cell differentiation. The crystal structure of PGI in the native form from rabbit muscle has been solved at a resolution of 2.5 A by a combination of multiple isomorphous replacement and multi-crystal averaging techniques. Comparison with published structures of rabbit PGI in complex with three inhibitors and with the substrate fructose 6-phosphate reveals a number of conformational changes that may be associated with catalytic function. These occur in the small domain around the sugar phosphate-binding site, in a small helix carrying His388 and in a helix near the C-terminal end. One of these may be the structural rearrangement that has been postulated to be the rate-limiting step for catalysis.
