Research progress of receptor protein FUNDC1 in mitophagy / 医学研究生学报

ABSTRACT

Mitochondria, which play an important role in cell metabolism, stress response and cell death, are the key organelles that regulate the energy balance of cells. Under the influence of internal and external environment, damaged or senescent mitochondria pose a serious threat to cell survival. Mitophagy refers to the selective elimination of dysfunctional mitochondria to maintain the homeostasis of the intracellular environment. FUN14 domain containing 1 (FUNDC1) is a newly discovered mitophagy receptor protein, which plays an important regulatory role in mediating mitophagy. This paper mainly reviews the recent research progress of FUNDC1 regulation mechanism and its pathophysiological significance in mitophagy.
