SLP-2 resides in the mitochondrial intermembrane space, where it interacts with Mfn2, a regulator of mitochondrial fusion, and regulates OPA1, a regulator of cristae junctions in mitochondria (left). SLP-2 expression is associated with increased OPA1 stability which in turn may contribute to cytochrome c retention due to tight junctions of cristae. Carcinogenesis is associated with elevated expression of SLP-2, enhancing cancer cell resistance to chemotherapeutics. SLP-2 inactivation triggers loss of mitochondrial membrane potential and proteolytic processing of OPA1 (right). In combination with mitochondrial stress, inactivation of SLP-2 can trigger apoptosis associated with DRP1 oligomerization and cytochrome c release.
