Multifunctional protein that plays a role in silencing host antiviral defenses and promoting viral transcription. Does not seem to be essential for HBV infection. May be directly involved in development of cirrhosis and liver cancer (hepatocellular carcinoma). Most of cytosolic activities involve modulation of cytosolic calcium. The effect on apoptosis is controversial depending on the cell types in which the studies have been conducted. May induce apoptosis by localizing in mitochondria and causing loss of mitochondrial membrane potential. May also modulate apoptosis by binding host CFLAR, a key regulator of the death-inducing signaling complex (DISC). Promotes viral transcription by using the host E3 ubiquitin ligase DDB1 to target the SMC5-SMC6 complex to proteasomal degradation. This host complex would otherwise bind to viral episomal DNA, and prevents its transcription. Moderately stimulates transcription of many different viral and cellular transcription elements. Promoters and enhancers stimulated by HBx contain DNA binding sites for NF-kappa-B, AP-1, AP-2, c-EBP, ATF/CREB, or the calcium-activated factor NF-AT.

Protein X also known as HBV protein X is a multifunctional protein with a molecular mass of approximately 17 kDa. It is an integral component of Hepatitis B virus (HBV) and expressed within infected host liver cells. Protein X influences viral replication by interacting with host cellular mechanisms specifically modulating transcriptional regulation and signaling pathways that can benefit viral persistence. Due to its versatile nature researchers study Protein X's diverse roles in the context of HBV infection.
The function of Protein X extends beyond viral replication. It plays a significant role in manipulating the host's immune response often suppressing antiviral activities which can allow the virus to evade the immune system. The interactions with cellular proteins may not always be direct as Protein X can be part of a larger viral replication complex. These interactions impact the host cell’s regulatory networks complicating the response to infection and facilitating chronic hepatitis conditions.
Protein X is involved in the regulation of cellular apoptosis and the modulation of the NF-kB signaling pathway. These pathways contribute to the survival and proliferation of infected cells and Protein X often interacts with host proteins like p53 and CREB to exert its effects. By affecting these pathways Protein X ensures the survival of the virus within the host promoting pathological conditions.
Protein X's impact is most closely associated with chronic Hepatitis B and related liver diseases. The protein's involvement in hepatocarcinogenesis highlights its oncogenic potential since it can promote the development of hepatocellular carcinoma (HCC). Interactions with proteins such as p53 highlight its role in oncogenic processes disrupting cell cycle regulation and apoptosis which can lead to uncontrolled cell growth and cancer progression.
