Mitochondria vary in morphology and function in different tissues, however little is known about their molecular diversity among cell types. To investigate mitochondrial diversity in vivo, we developed an efficient protocol to isolate cell type-specific mitochondria based on a new MitoTag mouse. We profiled the mitochondrial proteome of three major neural cell types in cerebellum and identified a substantial number of differential mitochondrial markers for these cell types in mice and humans. Based on predictions from these proteomes, we demonstrate that astrocytic mitochondria metabolize long-chain fatty acids more efficiently than neurons. Moreover, we identified Rmdn3 as a major determinant of ER-mitochondria proximity in Purkinje cells. Our novel approach enables exploring mitochondrial diversity on the functional and molecular level in many in vivo contexts.

Samples for mass spectrometry were obtained from 8- to 9-week-old, male mice. Mitochondria were immunopurified from cerebellum according to the described protocol with the alteration that the final mitochondrial pellet was washed twice in IB without EDTA and BSA. Sample were lysed in 100 µL SDT lysis buffer (4% w:v SDS, 100 mM DTT in 100 mM Tris-HCl pH 7.6) by heating for 5 min at 95°C and ultrasonication (Vialtweeter: 6 times for 30 s, 100% Amplitude, 50% cycle, max power; Hielscher Ultrasonics). ...
