Predicted to enable N-acetylglucosaminyldiphosphodolichol N-acetylglucosaminyltransferase activity and thiol-dependent deubiquitinase. Acts upstream of or within negative regulation of TORC1 signaling; negative regulation of neuron death; and regulation of synaptic plasticity. Located in cytoplasm. Is expressed in several structures, including forelimb bud; nervous system; and respiratory system. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 36. Orthologous to human ALG13 (ALG13 UDP-N-acetylglucosaminyltransferase subunit). [provided by Alliance of Genome Resources, Apr 2022]
