To address the role of Miro1 phosphorylation for regulating the ubiquitination of Miro in dopaminergic neuroblastoma cells, we tested the ability of phospho-null (S156A) and phospho-mimetic (S156E) mutants of Miro1 to be ubiquitinated upon mitochondrial damage. The gene discussed is RHOT1; the disease is neuroblastoma.
