COX7A2L/SCAFI and pre-complex III modify respiratory chain supercomplex formation in different mouse strains with a Bcs1l mutation
The COX7A2L (Supercomplex Assembly Factor I, SCAFI) protein has been proposed to be a mitochondrial supercomplex assembly factor required for respirasome (supercomplex containing complexes I, III, and IV) formation. In the C57BL/6 mouse strain a homozygous in-frame 6-base-pair deletion in the COX7a2l/SCAF1 gene resulting in unstable protein and suggesting loss of function was previously identified
