The GTPase Miro1 is tail anchored into the mitochondrial outer membrane and tethers mitochondria to molecular motors which is crucial for mitochondrial transport. Miro1 contains two EF hand, ion binding domains important for calcium sequestration. Miro1 is associated with Parkinson’s disease (PD) due to its suggested interaction with PINK1 and Parkin. Rare variants in RHOT1 (encoding Miro1) were found in PD patients but Miro1′s function in the brain is understudied. We gene edited three point mutations in healthy iPSCSEF hand R272Q was identified in a PD patient, S156A abolishes the proposed PINK1 phosphorylation site, K572R abolishes the main lysine targeted by pSer65-parkin.
