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. This evidence concerns the gene BICRA and cancer.
