African-specific polymorphisms in Plasmodium falciparum serine repeat antigen 5 in Uganda and Burkina Faso clinical samples do not interfere with antibody response to BK-SE36 vaccination [PDF]
BK-SE36, based on Plasmodium falciparum serine repeat antigen 5 (SERA5), is a blood-stage malaria vaccine candidate currently being evaluated in clinical trials.

The role of serine-type serine repeat antigen in Plasmodium yoelii blood stage development. [PDF]
A key step for the survival of the malaria parasite is the release from and subsequent invasion of erythrocytes by the merozoite. Differences in the efficiency of these two linked processes have a direct impact on overall parasite burden in the host and ...

Inhibitory potential of prodomain of Plasmodium falciparum protease serine repeat antigen 5 for asexual blood stages of parasite. [PDF]
Plasmodium falciparum serine repeat antigen 5 (SERA5) is a target for both drug and vaccine intervention against malaria. SERA5 is secreted in the parasitophorous vacuole where it is proteolytically processed before schizont rupture.

Calcium-dependent phosphorylation of Plasmodium falciparum serine repeat antigen 5 triggers merozoite egress. [PDF]
The human malaria parasite Plasmodium falciparum proliferates in red blood cells following repeated cycles of invasion, multiplication, and egress. P. falciparum serine repeat antigen 5 (PfSERA5), a putative serine protease, plays an important role in merozoite egress. However, regulation of its activity leading to merozoite egress is poorly understood.

Plasmodium berghei serine repeat antigen 3 (PbSERA3) is required for hepatic merozoite egress [PDF]
The asexual replicating intracellular stages of Plasmodium reside within the parasitophorous vacuole (PV) and become extracellular through an active, protease-mediated process known as egress.

Antibodies reactive to Plasmodium falciparum serine repeat antigen in children with Burkitt lymphoma from Ghana. [PDF]
AbstractThe role of protective immunity to Plasmodium falciparum (Pf) malaria in Burkitt lymphoma (BL) is unknown. We investigated the association between BL and antibodies reactive to SE36 antigen, a recombinant protein based on P. falciparum serine repeat antigen 5 gene, targeted by protective malaria immune responses. Cases were children (0–14 years)

Plasmodium knowlesi is the leading cause of malaria in Malaysia. Serine Repeat Antigens (SERAs) have an essential role in the parasite life cycle. However, genetic characterization on P. knowlesi SERA3 Ag2 (PkSERA3 Ag2) is lacking. In the present study, nucleotide diversity, natural selection, and haplotypes of PkSERA3 Ag2 in clinical samples from ...

Haplotype diversity of Plasmodium falciparum circumsporozoite protein prior to malaria vaccine implementation in Kaelé Health District, Cameroon, 2022–2023 [PDF]
Malaria remains a major public health concern in Cameroon, with Plasmodium falciparum responsible for most morbidity and mortality, particularly among children under five.

We report the isolation of cDNA clones for a Plasmodium falciparum gene that encodes the complete amino acid sequence of a previously identified exported blood stage antigen. The Mr of this antigen protein had been determined by sodium dodecylsulphate-polyacrylamide gel electrophoresis analysis, by different workers, to be 113,000, 126,000, and 140,000.

Previously, the Plasmodium falciparum serine repeat antigen has been shown to be protective in primate models of malaria immunity and also to be a target of in vitro parasite-inhibitory antibodies. To further define parasite-inhibitory epitopes a series of deletions from the amino-terminal 47-kDa domain of the serine repeat antigen (SERA) were ...
