Predicted to enable N-acetylglucosaminyldiphosphodolichol N-acetylglucosaminyltransferase activity and thiol-dependent deubiquitinase. Predicted to be involved in dolichol-linked oligosaccharide biosynthetic process and proteolysis. Predicted to act upstream of or within negative regulation of TORC1 signaling; negative regulation of neuron death; and regulation of synaptic plasticity. Predicted to be located in cytoplasm. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 36. Orthologous to human ALG13 (ALG13 UDP-N-acetylglucosaminyltransferase subunit).
