Probable neuronal cell surface protein thought to be involved in cell-cell-interactions (Probable). Confers protection against oxidative stress (PubMed:29346364). Plays a role in protecting dopaminergic neurons against oxidative stress-induced neurodegeneration (PubMed:29346364). Expressed in the pharynx, intestine, and in several cells in the head including dopaminergic neurons. Expressed in larvae and adults. Expressed in dopaminergic neurons in L4 larvae. Belongs to the type-B carboxylesterase/lipase family. Although glit-1 contains an extracellular carboxylesterase-like domain, the characteristic Ser-Glu-His catalytic triad present in acetylcholinesterase is replaced by two Asp residues and an Arg, suggesting that glit-1 lacks catalytic activity.
