General description
Protein X (UniProt: P69713; also known as HBx, Peptide X, pX) is encoded by the X gene (Gene ID: 944566) in Hepatitis B virus. Hepatitis B virus (HBV) contains seven main proteins, which include Core, pre-Core, Small S, Middle S, Large S, Polymerase, and the HBx protein. HBx, a multifunctional protein, although not essential for HBV infection, plays a role in silencing host antiviral defenses and promoting viral transcription. It facilitates the efficient replication of HBV by stimulating HBV gene expression from the cccDNA template. It is mainly localized in the cytoplasm with a small fraction detected in the nucleus. However, its expression level can also influence its cellular localization. It is predominantly nuclear when expressed in cells at very low levels but becomes largely cytoplasmic as its expression level increases. In cytoplasm, a minor fraction may also associate with mitochondria. Its mitochondrial targeting sequence is localized in amino acids 68-117. HBx has an N-terminal negative regulatory domain and its transactivation or coactivation of the C-terminal domain is reported to interfere with host cell signaling transduction pathways to help HBV replication. The best-characterized HBx binding partner is the cellular damage-specific DNA binding protein 1 (DDB1) and the interaction of HBx-DDB1 is essential for HBV replication. HBx promotes the degradation of the cellular structural maintenance of chromosomes 5/6 complex (Smc5/6), which directly binds DNA and entraps DNA plasmids. HBx is directly involved in development of cirrhosis and liver and hepatocellular carcinoma. (Ref.: Kornyeyev, D., et al. (2019). J. Virol. 93(16); e00248-19; Hwang, G-Y., et al. (2003). J. Clin.

HBx, a multifunctional regulatory protein, plays an essential role in the replication and pathogenesis of the hepatitis B virus (HBV). In this study, we found that in human hepatoma cells, the tumor suppressor p53 downregulates HBx via ubiquitin-dependent proteasomal degradation.
