Only eight members of the functional network were connected to anti-cancer drugs, including five tyrosine kinase receptors (MAST1 or Microtubule-associated serine/threonine-protein kinase 1, PDGFRA or Platelet-derived growth factor receptor alpha, BTK or Tyrosine-protein kinase, RAF1 or RAF proto-oncogene serine/threonine-protein kinase, and MAP4K3 or Mitogen-activated protein kinase kinase kinase kinase 3), the tubulin beta chain (TUBB), the histone deacetylase 3 (HDAC3), and carbonic anhydrase 6 (CA6) (Figure 9). Here, MAP2K3 is linked to cancer.
