Description

Mitochondria-eating protein (MIEAP, also known as spermatogenesis-associated protein 18), a p53-inducible protein, is a key regulator of mitochondrial quality that mediates the repair or degradation of unhealthy mitochondria in response to mitochondrial damage [PMID: 21264221]. It induces intra-mitochondrial lysosome-like organella that eliminate oxidised mitochondrial proteins without destroying the mitochondrial structure, leading to improvement in mitochondrial function [PMID: 21264221]. It is also involved in degradation of damaged mitochondria by promoting the formation of vacuole-like structures (named MIV), which engulf and degrade the mitochondria by accumulating lysosomes [PMID: 21264228].
