These domains enable its engagement in several signaling cascades and dynamic control. The pathophysiology of chronic myeloid leukemia (CML) is mainly driven by the BCR-ABL1 oncoprotein, arising from dysregulation of ABL1 kinase, namely through its fusion to the breakpoint cluster region (BCR) gene.

We initially screened 363 doxorubicin-binding proteins using protein microarrays; of these, 166 proteins with known PDB (Protein Data Bank) structures were selected for molecular docking to evaluate their binding energies. The binding energy distribution and residue enrichment analyses revealed that doxorubicin preferentially binds to specific residues at its binding sites, including serine, glycine, arginine, glutamic acid, lysine, aspartic acid, and leucine. These residues stabilize doxorubicin binding through hydrogen bonds, hydrophobic interactions, and electrostatic interactions. In addition, RUVBL1 (RuvB-like AAA ATPase 1) exhibited the highest integrated score from the protein microarray and molecular docking analyses. Furthermore, PPI (protein–protein interaction) network analysis and centrality calculations identified key proteins with potential regulatory roles, with MAPK1 (mitogen-activated protein kinase 1) exhibiting the highest betweenness centrality in the PPI network. Finally, molecular dynamics simulations of the RUVBL1- and MAPK1-doxorubicin complexes were conducted to evaluate the binding mechanisms.
