Phylogenetic and 2D/3D Analysis of HCV 1a NS4A Gene/Protein in Pakistani Isolates

BACKGROUND: The nonstructural protein NS4A of hepatitis C virus is composed of 54 amino acids. This small size protein has vital role in many cellular functions. The most important reported function is being a cofactor of viral enzymes serine protease and helicase. OBJECTIVES: The objective of this...

Sumario:BACKGROUND: The nonstructural protein NS4A of hepatitis C virus is composed of 54 amino acids. This small size protein has vital role in many cellular functions. The most important reported function is being a cofactor of viral enzymes serine protease and helicase. OBJECTIVES: The objective of this study was to analyze the phylogenetic variation, its impact in terms of translation and any functional change in protein structure at primary 2D/3D structure using computational tools from Pakistani patients isolates. MATERIALS AND METHODS: Patient sera infected with Hepatitis C virus, genotype 1A, were obtained from Molecular Diagnostics lab, CEMB, University of the Punjab Lahore by using BD Vacutainer collection tubes (Becton Dickenson). RESULTS: Phylogenetic analysis of the gene revealed that Pakistani 1a HCV strains are in the start of third cluster and there is a difference between inter Pakistani isolates at primary, secondary and tertiary levels. CONCLUSIONS: Mutations were present in the central domain of NS4A (amino acids 21 - 34).
