Following virus entry into host cell, provides nuclear import of HDV RNPs thanks to its nuclear localization signal. Needs co-infection with hepatitis B virus to provide surface proteins, otherwise there is no packaging or budding. Packages the HDV ribonucleoprotein in hepatitis B virus empty particles. Interacts with both HDV genomic RNA and cytoplasmic tail of HBsAg. May inhibit viral RNA replication. Hepatitis delta virus genotype I (HDV) Large delta antigen Protein (His & Myc) is expressed in yeast with N-10xHis and C-Myc tag. The predicted molecular weight is 27.7 kDa and the accession number is P0C6L6.

Plays a role in the inhibition of host antibody-mediated neutralization without blocking viral cell entry.; Forms an icosahedral capsid with a T=1 symmetry and a 34 nm diameter. The capsid is composed of 60 copies linked to each other. Binds to the 5' end of the genomic RNA to mediate genome encapsidation. Binds to heparin surface proteoglycans (HSPGs) to mediate viral entry. Additionally, the interactions with host ASGR1 and ASGR2 facilitate viral infection of hepatocytes. Hepatitis E virus genotype 1 (HEV-1) Secreted protein ORF2 (His) is expressed in Baculovirus insect cells with N-10xHis tag. The predicted molecular weight is 71.3 kDa and the accession number is Q68985.

Promotes both transcription and replication of genomic RNA. Following virus entry into host cell, provides nuclear import of HDV RNPs thanks to its nuclear localization signal. May interact with host RNA polymerase II thereby changing its template requirement from DNA to RNA. RNA pol II complex would then acts as an RNA-directed RNA polymerase, and transcribe and replicate HDV genome. Hepatitis delta virus genotype I (HDV) Small delta antigen Protein (His & Myc) is expressed in yeast with N-6xHis and C-Myc tag. The predicted molecular weight is 25.4 kDa and the accession number is P06934.

Major viral capsid protein that encapsidates the viral genome. Binds to the 5' end of the genomic RNA. Hepatitis E virus genotype 3 (HEV-3) Capsid protein (His) is expressed in yeast with N-6xHis tag. The predicted molecular weight is 29.3 kDa and the accession number is Q9YLQ9.

Plays critical roles in the final steps of viral release by interacting with host TSG101, a member of the vacuolar protein-sorting pathway and using other cellular host proteins involved in vesicle formation pathway. Acts also as a viroporin and forms ion conductive pores allowing viral particle release. Impairs the generation of type I interferon by downregulating host TLR3 and TLR7 as well as their downstream signaling pathways. Hepatitis E virus genotype 1 (HEV-1) Protein ORF3 (His & SUMO) is expressed in E. coli expression system with N-6xHis-SUMO tag. The predicted molecular weight is 27.8 kDa and the accession number is O90299.

NQO1 gene is a member of the NAD(P)H dehydrogenase (quinone) family and encodes a cytoplasmic 2-electron reductase. NQO1 forms homodimers and reduces quinones to hydroquinones. NQO1's enzymatic activity prevents the one-electron reduction of quinones that results in the production of radical species. Mutations in the NQO1 gene have been associated with tardive dyskinesia (TD), an increased risk of hematotoxicity after exposure to benzene, and susceptibility to various forms of cancer. Altered expression of NQO1 has been seen in many tumors and is also associated with Alzheimer's disease (AD). Alternate transcriptional splice variants, encoding different isoforms, have been characterized. Recent pharmacological research suggests the feasibility of genotype-directed redox chemotherapeutic intervention targeting NQO1 breast cancer, a common missense genotype encoding a functionally impaired NQO1 protein.

Sulfate conjugation catalyzed by cytosolic sulfotransferase (SULT) enzymes. The SULTs are Phase II drug-metabolizing enzymes that catalyze the addition of a sulfuryl moiety to both endogenous compounds, including steroids and neurotransmitters, and certain xenobiotics, including N-hydroxy-2-acetylaminoflourine and phenolic compounds, like alpha-naphthol. SULTs may be involved in the individual genetic disposition, species differences, and organotropisms for toxicological effects of chemicals. Particularly SULT1A1 (Sulfotransferase family, cytosolic, 1A, phenol-preferring, member 1), a member of the sulfotransferase 1 subfamily, which is a major pathway for drug metabolism in humans. Humans have at least 10 functional SULT genes. There has been an explosion in information on sulfotransferase polymorphisms and their functional consequences. An Arg213His polymorphism in SULT1A1 has a strong influence on the level of enzyme protein and activity in platelets, which have been widely used for phenotyping. Statistically significant associations were observed between the SULT1A1 genotype (Arg213His) and age, obesity and certain neoplasias (mammary, pulmonary, esophageal and urothelial cancer). Furthermore, the polymorphism of the SULT1A1 may be closely associated with breast cancer.
