Abstract: A function of cyclin-dependent kinase 12 (CDK12) as a biomarker for a human epidermal growth factor receptor 2 (HER2)-positive cancer and anti-HER2 therapy, and a use of the CDK12 are provided. The CDK12 may be used for companion diagnostics of a HER2-targeted therapeutic agent for a subject having HER2+ cancer as a prognostic factor and a predictive factor for response of the subject to the anti-HER2-targeted therapeutic agent in HER2+ cancer, or used to check the probability of expressing resistance to the HER2-targeted therapeutic agent. When the CDK12 is amplified or expressed at a level higher than a reference value, the CDK12 may be suppressed to overcome the resistance to the HER2 therapeutic agent and improve a therapeutic effect, thereby improving the therapeutic efficiency of HER2-positive cancer.
