Abstract:
Stomatin-like protein-2 (SLP-2) is a mitochondrial-associated protein that is abundant in cardiomyocytes. Many reports have shown that SLP-2 plays an important role in mitochondria. The treatment of mitochondrial cardiomyopathy (MCM) needs further improvement, so the relationship between SLP-2 and MCM is worth exploring. This study reviewed some protective mechanisms of SLP-2 on mitochondria. Published studies have shown that SLP-2 protects mitochondria by stabilising the function of optic atrophy 1 (OPA1), promoting mitofusin (Mfn) 2 expression, interacting with prohibitins and cardiolipin, forming SLP-2-PARL-YME1L (SPY) complex, and stabilising respiratory chain complexes, suggesting that SLP-2 is a new potential target for the treatment of MCM. However, the specific mechanism of SLP-2 needs to be confirmed by further research.

Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
