Description:
Plasmodium vivax is one of the four malaria parasites that cause disease in humans. The structure of the immunodominant repeating peptide of the circumsporozoite (CS) protein of P. vivax was determined. A fragment of P. vivax DNA that encodes this tandemly repeating epitope was isolated by use of an oligonucleotide probe whose sequence is thought to be conserved in CS protein genes. DNA sequence analysis of the P. vivax clone indicates that the CS repeat is nine amino acids in length (Gly-Asp-Arg-Ala-Asp-Gly-Gln-Pro-Ala). The structure of the repeating region was confirmed with synthetic peptides and monoclonal antibodies directed against P. vivax sporozoites. This information should allow synthesis of a vaccine for P. vivax that is similar to the one being tested for P. falciparum.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McCutchan, T F -- Lal, A A -- de la Cruz, V F -- Miller, L H -- Maloy, W L -- Charoenvit, Y -- Beaudoin, R L -- Guerry, P -- Wistar, R Jr -- Hoffman, S L -- New York, N.Y. -- Science. 1985 Dec 20;230(4732):1381-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2416057" target="_blank"〉PubMed〈/a〉
