genetic variation and selection of domain i of the plasmodium vivax apical membrane antigen-1(ama-1) gene in clinical isolates from iran.
background: apical membrane antigen 1 (ama-1) is positioned on the surface of merozoite and it may play a role in attack to red blood cells. the mainaim of present study was to determine the genetic variation, as well as, to detect of selection at domain i of ama-1 gene plasmodium vivax isolates in iran. methods: blood samples were collected from 58 patients positive for p. vivax ,mono infectio...
متن کاملGenetic diversity and effect of natural selection at apical membrane antigen-1 (AMA-1) among Iranian Plasmodium vivax isolates.
Apical membrane antigen-1 (AMA-1) of Plasmodium vivax Grassi et Feletti, 1890 is a promising malaria vaccine candidate. However, antigenic variation is a major problem to design a universal malaria vaccine. Hence, detailed understanding of the pvama-1 gene polymorphism can provide conductive information on this potential vaccine component. Therefore, this study investigated the extent of geneti...
متن کاملDomain III of Plasmodium falciparum apical membrane antigen 1 binds to the erythrocyte membrane protein Kx.
Plasmodium falciparum apical membrane antigen 1 (AMA1) is located in the merozoite micronemes, an organelle that contains receptors for invasion, suggesting that AMA1 may play a role in this process. However, direct evidence that P. falciparum AMA1 binds to human erythrocytes is lacking. In this study, we determined that domain III of AMA1 binds to the erythrocyte membrane protein, Kx, and that...
متن کاملAnalysis of Plasmodium vivax Apical Membrane Antigen-1 (PvAMA-1) Haplotypes among Iranian Isolates
Plasmodium vivax apical membrane antigen-1(PvAMA-1) is a surface protein with polymorphic sites. This study was aimed to analyze the polymorphic amino acid residues at PvAMA-1 in different infected age groups. 92 blood samples were collected from south and southeast of Iran. The DNA coding for the domain I (DI), DII, and partial DIII of this antigen was amplified by Nested-PCR, and sequenced. N...
متن کاملStrong diversifying selection on domains of the Plasmodium falciparum apical membrane antigen 1 gene.
The surface-accessible ectodomain region of the Plasmodium falciparum apical membrane antigen 1 (AMA1) is a malaria vaccine candidate. The amino acid sequence may be under selection from naturally acquired immune responses, and previous analyses with a small number of allele sequences indicate a non-neutral pattern of nucleotide variation. To investigate whether there is selection to maintain p...
