Title

SEQUENCE ANALYSIS OF DIFFERENT DOMAINS OF PLASMODIUM VIVAX APICAL MEMBRANE ANTIGEN (PVAMA-1 GENE) LOCUS IN IRAN

Pages

  26-31

Abstract

 Background: PLASMODIUM VIVAX is responsible for approximately 80 million malaria cases in the world. APICAL MEMBRANE ANTIGEN1 (AMA-1) is a type I integral membrane protein present in all Plasmodium species. AMA-1 interferes in critical steps of invasion of human hepatocytes by sporozoites and red blood cells by merozoites and is one of the most immunodominant antigens for eliciting a protective immune response in human. It is considered as a promising antigen for inclusion in a vaccine against P. vivax. Since more knowledge is needed to lighten the scope of such antigen we compared genetic variation in P. vivax AMA-1from an IRANian isolate with those reported from some of the other malarious countries so far.Methods: P. vivax genomic DNA was extracted from the whole blood of an IRANian patient with patent P. vivax infection. The nucleotide sequence for 446 amino acid (AA) residues (42-488 of PvAMA-1) was amplified by PCR and cloned in pUC19 vector for sequencing.Results: Sequence analysis of the antigen showed a high degree of identity (99%) with strong homology to the PvAMA-1 gene of P. vivax S3 and SKO814 isolates from India and Korea (Asian isolates) respectively, and 96% similarity with P. vivax Sal-1 AMA-1 gene from El Salvador.Conclusions: We cloned and characterized three domains of PvAMA-1 gene from an IRANian patient.Predicted protein sequence of this gene showed some discrepancies in corresponding protein in comparing with similar genes reported from other malarious countries.
