Abstract:
In spite of a decrease in malaria cases, the threat of malaria due to Plasmodium falciparum still prevails. The sequencing of Plasmodium falciparum reveals that approximately 60% of the Plasmodium genes code for hypothetical/putative proteins. Here we report an in silico characterization and localization of one such protein. This was encoded by one of the hub genes, in a weighted gene co-expression based systems network, from in-vivo samples of patients suffering from uncomplicated malaria or complicated malaria disease like jaundice and jaundice with renal failure. Interestingly, the protein PF3D7_0406000 (PFD0300w) is classified as a conserved protein of unknown function and shows no identity with any protein from the human host. The transcriptomic data shows up-regulation of transcripts in cases of malaria induced disease complications. PFD0300w peptide antibody based immunolocalization studies using a, gametocyte producing P. falciparum strain RKL-9, shows presence of the protein in the cytoplasm of both asexual and sexual stage parasites.
