Protein Domain : Hepatitus C virus, Non-structural 5a protein, C-terminal IPR024350

Type  Domain
Description  Although Hepatitis A virus, Hepatitis B virus, and Hepatitis C virus have similar names, because they all cause liver inflammation, these are distinctly different viruses both genetically and clinically. The Hepatitis C virus (HCV) is a small (50-80 nm in diameter), enveloped, single-stranded, positive sense RNA virus. It is member of the family Flaviviridae. There are seven genotypes and a number of subtypes with diverse geographic distributions. The genome of HCV consists of a single open reading frame. At the 5' and 3' ends of the RNA are the UTR regions that are not translated into proteins but are important to translation and replication of the viral RNA. The 5' UTR has a ribosome binding site (IRES - Internal ribosome entry site) that starts the translation of unique polyprotein that is later cut by cellular and viral proteases into 10 active structural and non-structural smaller proteins [ ]. This entry represents the C-terminal region of the Hepatitus C virus, NS5a protein. The molecular function of the non-structural 5a protein is uncertain. The NS5a protein is phosphorylated when expressed in mammalian cells. It is thought to interact with the dsRNA dependent (interferon inducible) kinase PKR [ , ].
