Activity summary

The Hepatitis B Virus Surface Antigen commonly known as HBsAg is an important structural protein of the Hepatitis B Virus (HBV). This antigen is also referred to as Hep B surf Ab. Designed with a mass of approximately 24 kDa HBsAg is expressed extensively in the liver tissues of individuals infected with Hepatitis B. It represents the major component of the virus's envelope and plays a role in the formation of subviral particles. Several commercial antibodies such as Hepatitis antibodies and HBV antibodies target HBsAg for analytical and diagnostic purposes in laboratories.

Biological function summary

The Hepatitis B Virus Surface Antigen interacts with the host's immune system and assists in viral replication. HBsAg is not part of a larger protein complex. Rather it circulates as free particles known as 3e-7 and 3e-7 Hepatitis B antigens which are abundant in the blood serum during active infection. These particles act as decoys distracting the host's immune defense and facilitating the persistence of the infection. The production and clearance of HBsAg serve as important indicators of HBV infection status and disease progression.

Pathways

Hepatitis B Virus Surface Antigen plays an integral role in the HBV life cycle particularly within the viral entry and replication pathways. It shares a functional relationship with the HB5 protein which is important for viral particle assembly and release. The interactions between HBsAg and host proteins influence viral propagation and subsequently the overall pathway of HBV infection within hepatocytes. Understanding these interactions can aid in the development of therapeutic interventions to disrupt the viral lifecycle.

Associated diseases and disorders

Hepatitis B Virus Surface Antigen is directly associated with chronic Hepatitis B infection and hepatocellular carcinoma. Chronic Hepatitis B characterized by the prolonged presence of HBsAg can advance to liver cirrhosis and cancer if untreated. The antigen's persistence is often monitored alongside liver enzymes and other markers such as Hepatitis B antibodies (Hep B antibodies) to assess disease progression and treatment efficacy. Effective management of HBsAg levels helps mitigate the risk and severity of these severe liver diseases.
