Drosophila gliotactin (Gli) is a 109-kDa transmembrane, cholinesterase-like adhesion molecule (CLAM), expressed in peripheral glia, that is crucial for formation of the blood-nerve barrier. The intracellular portion (Gli-cyt) was cloned and expressed in the cytosolic fraction of Escherichia coli BLR(DE3) at 45 mg/L and purified by Ni-NTA (nitrilotriacetic acid) chromatography.
