MYBBP1A and renal carcinoma: After confirming that MYBBP1A was located in the nucleolus of renal cancer cells (Figure S4), as it has been described in other cell types [5,6,11], we observed co-localization of c-MYB and MYBBP1A in the nucleus, specifically nucleoli, of cells with high levels of c-MYB protein (Figure 1C).
