Glucose is hugely important; it is a source of carbon atoms for the biosynthesis of other cellular molecules, it is an important building block in its own right, ... The second step of glycolysis is phosphoglucose isomerase (PGI). The protein has different functions inside and outside the cell. In the cytoplasm, the protein is involved in glycolysis and gluconeogenesis, as well as the pentose phosphate pathway. Outside the cell, it functions as a neurotrophic factor for spinal and sensory neurons, called neuroleukin.
