The human IFN-inducible p53 target gene TRIM22 colocalizes with the centrosome independently of cell cycle phase.
TRIM22 (Staf50), a member of the TRIM protein family, is an interferon (IFN)-inducible protein as well as a p53 target gene. The function of TRIM22 is largely unknown, but TRIM22 is suggested to play a role in viral defense by restriction of viral replication. In addition, TRIM22 may function as a ubiquitin E3 ligase. In contrast to previous reports showing solely cytoplasmic localization of exoge
