A Novel Polypeptide CAPG-171aa Encoded by circCAPG Plays a Critical Role in Triple-Negative Breast Cancer

CircRNA expression data in TNBC were reanalyzed and then circCAPG was selected for further study. To identify the polypeptide-coding function of circCAPG, a series of experiments, such as mass spectrometry and dual-luciferase reporter assays were conducted.
