CKMT1B and cancer: Moreover, leveraging gene expression and drug sensitivity data from the Cancer Dependency Map Project (Depmap) at the Broad Institute, we identified strong positive associations between the expression of CKMT1A, CKMT1B, and CKB, and the cell's sensitivity to Oligomycin A, another inhibitor of F1F0 ATP synthase (Figure S1D–F, Supporting Information).
