Enables protease binding activity. Predicted to be involved in electron transport coupled proton transport; mitochondrial electron transport, NADH to ubiquinone; and mitochondrial respiratory chain complex I assembly. Located in neuron projection; neuronal cell body; and synaptic membrane. Human ortholog(s) of this gene implicated in nuclear type mitochondrial complex I deficiency 3. Orthologous to human NDUFS7 (NADH:ubiquinone oxidoreductase core subunit S7). [provided by Alliance of Genome Resources, Apr 2022]
