Mitophagy‐associated proteins (MAPs), including PTEN‐induced putative kinase 1 (PINK1), Parkin, phosphoglycerate mutase 5 (PGAM5), BCL2 interacting protein 3 (BNIP3), and phosphorylated‐TBK1 (p‐TBK1), are, to our best knowledge, not well studied as a panel of biomarkers of neurodegeneration in PD. Here, BNIP3 is linked to Parkinson disease.
