Serine/threonine-protein kinase PINK1, mitochondrial
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
Highly expressed in heart, skeletal muscle and testis, and at lower levels in brain, placenta, liver, kidney, pancreas, prostate, ovary and small intestine. Present in the embryonic testis from an early stage of development.
Autophosphorylation at Ser-228 and Ser-402 is essential for Parkin/PRKN recruitment to depolarized mitochondria.; Two shorter forms of 55 kDa and 48 kDa seem to be produced by proteolytic cleavage and localize mainly in cytosol. Processed into a 52 kDa mature form by PARL or AFG3L2 following the cleavage by mitochondrial-processing peptidase (MPP) during mitochondrial import. In depolarized mitochondria, cleaved by OMA1 that acts as a backup protease, promoting its subsequent degradation by the proteasome.
Mitochondrion outer membrane; Single-pass membrane protein. Note=Localizes mostly in mitochondrion and the 2 proteolytic processed fragments of 55 kDa and 48 kDa localize mainly in cytosol. When mitochondria lose mitochondrial membrane potential following damage, PINK1 import is arrested, which induces its accumulation in the outer mitochondrial membrane, where it acquires kinase activity.
Protects against mitochondrial dysfunction during cellular stress by phosphorylating mitochondrial proteins. Involved in the clearance of damaged mitochondria via selective autophagy (mitophagy) by mediating activation and translocation of PRKN. Targets PRKN to dysfunctional depolarized mitochondria through the phosphorylation of MFN2. Activates PRKN in 2 steps: (1) by mediating phosphorylation at 'Ser-65' of PRKN and (2) mediating phosphorylation of ubiquitin, converting PRKN to its fully-active form. Required for ubiquinone reduction by mitochondrial complex I by mediating phosphorylation of complex I subunit NDUFA10 (By similarity).
