BRD4 and cancer: In addition, the BD domain and PDID domain are conserved in BET family proteins, previous studies characterized BRD9‐GLTSCR1 interaction as the SWI/SNF complex through IP‐mass spectrometry,45 and GLTSCR1 was also predicted with a BRD3 recognition region in other cell model.19 Therefore, the BRD4‐independent roles of GLTSCR1 in cancer progression and in other diseases need further exploration.
