Abstract:
CISD2, the causative gene for Wolfram syndrome 2 (WFS2), is a previously uncharacterized novel gene. Using a mouse genetic approach, this work demonstrated for the first time that Cisd2 is involved in mammalian life span control. Cisd2 deficiency in mice leads to mitochondrial breakdown and dysfunction; this is accompanied by cell death with autophagic features and these events precede the two earliest manifestations of nerve and muscle degeneration. Together, they lead to a panel of phenotypic features suggestive of premature aging. This work effectively links Cisd2 gene function, mitochondrial integrity and aging in mammals.

Translocation of Proteins into the Mitochondria
Sorting of outer membrane proteins:
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,...
