Indeed, currently, 37 kinase inhibitors have received FDA approval for the treatment of cancer, and about 150 kinase-targeted drugs are in various clinical phase trials [14].The human protein kinases numbering 518, constitute one of the largest family of the human genome, representing 1.7% of the genome [15].These protein kinases are subdivided into two categories: the first,with 478 families, has typical eukaryotic catalytic domains (ePKs), and the second, contains 40 families with atypical catalytic domains [16]. The gene discussed is WEE1; the disease is cancer.
