HBV Gene Functions

P gene product

Function
These genes are mainly responsible for multifunctional enzyme. This means these enzymes has more than one active site and can perform 2 enzymes activity. This enzyme previews a DNA polymerase activity allows copying RNA templates. DNA replications also occur to synthesis new strand of DNA. DNA binding allows protein to bind to the DNA to change and alter the gene expression. It is an interaction process of the virus to the host cell to reproduce. Thus the above enzymes are used in this process. In ligand process, it promotes ions binding to the protein. DNA polymerase repairs the DNA when there is error. In molecular function, ribonuclease activity is undergoing as well.

S gene product

This gene involved in the viral reproduction and replication of viral genome.Virion is virus component with its DNA or RNA core and protein coat as it surrounds the bilayer lipid known as virion membrane. It helps in attachment of the cell to infect a host cell in order to reproduce. It is the gene responsible for them to reproduce next generation.

X gene product
X gene involved in polymerase and precore genes. It send the message to the repeating cycle, and allows transactivating functions.

Viral genome replication sometimes involved in the viral nucleotide metabolism. Protein involved in this gene also responsible for the apoptosis which is the programmed cell death. This is to allow younger and new cells to produce.

C gene product
Pathogenesis are relate to the core of antigen and protein to cause a disease. This is a molecular activity which happens inside and outside the cell. The outside layer is the host lipid protein while inside is the DNA genome. The capsid is considered as a polypedtide.Then lastly the viral capsid functions as the core antigen.

3215P gene product
This gene function is DNA replication. It is a process of synthesis a new strand using DNA template. It is also a DNA interaction of protein terminal and DNA region parts. It is associated with reverse transcriptase process.
