Mice whole body CBL depletion improved insulin sensitivity and glucose clearance, however, the precise mechanisms remain unknown. We depleted either CBL or its associated protein SORBS1/CAP independently in my-ocytes and assessed mitochondrial function and metabolism compared to control cells. CBL and CAP-depleted cells showed increased mitochondrial mass with greater proton leak. Mitochondrial respiratory complex I activity and assembly into respirasomes were reduced. Proteome profiling revealed alterations in proteins involved in glycolysis and fatty acid degradation. Our findings demonstrate CBL/CAP pathway couples insulin signalling to efficient mitochondrial respiratory function and metabolism in muscle. cc-by (c) Aye, Cho-Cho et al., 2023 https://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Mitocondris Resistència a la insulina Glucosa Mitochondria Insulin resistance Glucose CBL/CAP is essential for mitochondria respiration complex I assembly and bioenergetics efficiency in muscle cells. info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion
