Mitophagy is critical for cell homeostasis. Externalization of the inner
mitochondrial membrane phospholipid, cardiolipin (CL), to the surface of the
outer mitochondrial membrane (OMM) was identified as a mitophageal signal
recognized by the microtubule-associated protein 1 light chain 3. However, the
CL-translocating machinery remains unknown. Here we demonstrate that a hexameric
intermembrane space protein, NDPK-D (or NM23-H4), binds CL and facilitates its
redistribution to the OMM. We found that mitophagy induced by a protonophoric
uncoupler, carbonyl cyanide m-chlorophenylhydrazone (CCCP), caused
externalization of CL to the surface of mitochondria in murine lung epithelial
MLE-12 cells and human cervical adenocarcinoma HeLa cells. RNAi knockdown of
endogenous NDPK-D decreased CCCP-induced CL externalization and mitochondrial
degradation. A R90D NDPK-D mutant that does not bind CL was inactive in promoting
mitophagy. Similarly, rotenone and 6-hydroxydopamine triggered mitophagy in
SH-SY5Y cells was also suppressed by knocking down of NDPK-D. In situ proximity
ligation assay (PLA) showed that mitophagy-inducing CL-transfer activity of
NDPK-D is closely associated with the dynamin-like GTPase OPA1, implicating
fission-fusion dynamics in mitophagy regulation.
