Overview
PINK1 Protects against mitochondrial dysfunction during cellular stress, potentially by phosphorylating mitochondrial proteins. Involved in the clearance of damaged mitochondria via selective autophagy (mitophagy). It is necessary for PARK2 recruitment to dysfunctional mitochondria to initiate their degradation. Interats with PARK2. 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. Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
