Abstract:
Cells selectively scavenge redundant or damaged mitochondria by mitophagy, which is an important mechanism of mitochondrial quality control. Recent studies have shown that mitophagy is mainly regulated by autophagy-related genes (Atgs) in yeast cells, while mitochondrial membrane associated proteins such as PTEN-induced putative kinase 1 (PINK1), NIX/BNIP3L, BNIP3, FUN14 domain containing 1 (FUNDC1), FKBP8/FKBP38, Bcl-2-like protein 13 (Bcl2L13), nucleotide binding domain and leucine-rich-repeat-containing proteins X1 (NLRX1), prohibitin 2 (PHB2) and lipids such as cardiolipin (CL) are the key mitophagic receptors in mammalian cells, which can selectively recognize damaged mitochondria, recruit them into isolation membranes by binding to microtubule-associated protein 1 light chain 3 (LC3) or γ-aminobutyric acid receptor-associated protein (GABARAP), and then fuse with lysosomes to eliminate the trapped mitochondria. This article reviews recent research progress of mitophagy-related receptor proteins.
