GOPC, also known as PIST, is a PDZ domain-containing Golgi protein. This protein functions as a homooligomer that interacts with a variety of proteins and plays a role in intracellular protein trafficking and degradation. Additionally, GOPC is thought to regulate ionic currents via membrane channel modification and may also play a role in autophagy. Chromosomal aberrations in the gene encoding GOPC are found in glioblastoma multiform (GBM), a common and aggressive form of brain tumor, suggesting a role for mutated PIST in carcinogenesis. Recombinant GOPC protein was expressed in E. coli and purified by using conventional chromatography techniques. Recombinant protein corresponding to aa278-454 of human GOPC fused to His-Tag expressed in E. coli.
