GlycoErase™ GPI Knockout CHO-K1 Cell Line (CAT#: GLJF-0825-JF287)

Description	GlycoErase™ GPI knockout CHO-K1 cell line is a Chinese hamster ovary (CHO-K1) model in which GPI expression has been eliminated. GPI encodes glucose phosphate isomerase, a multifunctional "moonlighting" protein that functions as a glycolytic enzyme intracellularly, and extracellularly acts as neuroleukin, autocrine motility factor, and angiogenic factor. Deficiency is linked to hemolytic anemia and neurological impairment. This knockout model provides a versatile system to study glycolysis, tumor-secreted factors, neurotrophic signaling, and immune regulation, with applications in oncology, neurobiology, and metabolic disease research.

Summary	This gene encodes a member of the glucose phosphate isomerase protein family. The encoded protein has been identified as a moonlighting protein based on its ability to perform mechanistically distinct functions. In the cytoplasm, the gene product functions as a glycolytic enzyme (glucose-6-phosphate isomerase) that interconverts glucose-6-phosphate and fructose-6-phosphate. Extracellularly, the encoded protein (also referred to as neuroleukin) functions as a neurotrophic factor that promotes survival of skeletal motor neurons and sensory neurons, and as a lymphokine that induces immunoglobulin secretion. The encoded protein is also referred to as autocrine motility factor based on an additional function as a tumor-secreted cytokine and angiogenic factor. Defects in this gene are the cause of nonspherocytic hemolytic anemia and a severe enzyme deficiency can be associated with hydrops fetalis, immediate neonatal death and neurological impairment. Alternative splicing results in multiple transcript variants.
