Proteomic analysis of MCL-1 interactors in liver


ABSTRACT: Mcl1-conditional mice were injected with AAV-LP1-Cre to delete endogenous MCL-1 and with AAV-LP1-Mcl1Flag (FLINT) or AAV-LP1-GFP (wt control). After 14 days, mitochondria were harvest from mouse livers and subjected to anti-FLAG immunoprecipitation. Immune complexes were subjected to LC MS/MS mass spectrometry. Two independent liver mitochondria immunoprecipitations were run in parallel.

MCL-1 is essential for promoting the survival of many normal cell lineages and confers survival and chemoresistance in cancer. Beyond apoptosis regulation, MCL-1 has been linked to modulating mitochondrial metabolism, but the mechanism(s) by which it does so are unclear. Here, we show in tissues and cells that MCL-1 supports essential steps in long-chain (but not short-chain) fatty acid β-oxidation (FAO) through its binding to specific long-chain acyl-coenzyme A (CoA) synthetases of the ACSL fam  ...[more]
