In Silico Prediction and Docking of Tertiary Structure of Multifunctional Protein X of Hepatitis B Virus
Hepatitis B virus (HBV) infection is a universal health problem and may result into acute, fulminant, chronic hepatitis liver cirrhosis, or hepatocellular carcinoma. Sequence for protein X of HBV was retrieved from Uniprot database. ProtParam from ExPAsy server was used to investigate the physicochemical properties of the protein. Homology modeling was carried out using Phyre2 server, and refin...
متن کاملExpression of hepatitis B virus X protein does not alter the accumulation of spontaneous mutations in transgenic mice.
Chronic infection with hepatitis B virus (HBV) is one of the major etiological factors in the development of human hepatocellular carcinoma. Transgenic mice that express the HBV X protein (HBx) have previously been shown to be more sensitive to the effects of hepatocarcinogens, although the mechanism for this cofactor role remains unknown. The ability of HBx to inhibit DNA repair in transiently...
متن کاملMutant p53 but not hepatitis B virus X protein is present in hepatitis B virus-related human hepatocellular carcinoma.
Hepatitis B virus (HBV) X protein is thought to play an important role in the development of hepatocellular carcinoma. Recent studies on a transgenic mouse tumor model suggest that HBV X protein may contribute to transformation by binding to and inactivating the cellular growth suppressor protein p53. We have studied 31 hepatocellular carcinoma tissues from Chinese patients for the possible occ...
متن کاملHepatitis B virus splice-generated protein induces T-cell responses in HLA-transgenic mice and hepatitis B virus-infected patients.
Hepatitis B virus splice-generated protein (HBSP), encoded by a spliced hepatitis B virus RNA, was recently identified in liver biopsy specimens from patients with chronic active hepatitis B. We investigated the possible generation of immunogenic peptides by the processing of this protein in vivo. We identified a panel of potential epitopes in HBSP by using predictive computational algorithms f...
متن کاملHepatitis B virus X protein is not central to the viral life cycle in vitro.
The hepatitis B x (HBx) gene is the smallest open reading frame of the hepatitis B virus (HBV) genome. It is conserved among all mammalian hepadnaviruses and is expressed during viral infection. While the HBx protein (pX) has been shown to trans-activate the transcription of a wide range of viral and cellular genes and to induce liver cancer in transgenic mice, the significance of pX for the li...
