Plasmodium knowlesi is a zoonotic malaria parasite that can infect both macaque monkeys and humans. Several key proteins produced by this parasite play critical roles in pathogenesis and may be important targets for drug and vaccine development.

One such protein is the Erythrocyte-binding protein, which is involved in the invasion of erythrocytes by the parasite. SICA antigen and SICA-like antigen are also critical in erythrocyte invasion, while the hypothetical malaria antigen and Blood-stage antigen 41-3 are involved in the development of the parasite within the erythrocytes.

The Transmission-blocking target antigen s230 is involved in blocking the transmission of the parasite between human hosts and mosquitoes, while the Tryptophan-threonine rich antigen is thought to be involved in immune evasion. The 41-2 protein antigen- homolog is another key protein in the pathogenesis of P. knowlesi.

Liver stage antigen 3 and Pfs230 are critical in the development of the parasite in the liver and may be important targets for liver-stage vaccines. Additionally, Circumsporozoite-related antigen, Malaria antigen, Erythrocyte binding antigen, Apical merozoite antigen 1, and C-13 antigen all play critical roles in the pathogenesis of P. knowlesi.

Understanding the complex protein structures and roles of Plasmodium knowlesi is crucial in developing effective treatment and prevention strategies for malaria. By identifying key proteins and their functions, researchers can work to develop targeted therapies and vaccines to combat this deadly disease.

The use of cDNA and recombinant antigens from P. knowlesi has become an important tool in the diagnosis of human malaria caused by this species. cDNA and recombinant antigens can be used to detect the presence of the parasite in the blood, providing a more specific diagnosis than traditional microscopy. Additionally, recombinant antigens can be used to develop more specific and sensitive immunoassays, such as enzyme-linked immunosorbent assays (ELISAs) and lateral flow assays, for the rapid and specific detection of P. knowlesi in a clinical sample. Thus, the use of cDNA and recombinant antigens from P. knowlesi has enabled the more accurate and timely diagnosis of human malaria caused by this species.

The use of recombinant proteins/cDNA in academic research and therapeutic applications has skyrocketed. However, in heterologous expression systems, successful recombinant protein expression is dependent on a variety of factors, including codon preference, RNA secondary structure, and GC content. When compared to pre-optimization, more and more experimental results demonstrated that the expression level was dramatically increased, ranging from two to hundred times depending on the gene. Bioclone has created a proprietary technology platform that has resulted in the creation of over 6,000 artificially synthesized codon-optimized cDNA clones (cloned in E. coli expression Vector), which are ready for production of the recombinant proteins.
