566-706 2.56e-26

PFEMP1 DBL domain; PfEMP1 (Plasmodium falciparum erythrocyte membrane protein) has been identified as the rosetting ligand of the malaria parasite P. falciparum. Rosetting is the adhesion of infected erythrocytes with uninfected erythrocytes in the vasculature of the infected organ, and is associated with severe malaria. PfEMP1 interacts with Complement Receptor One on uninfected erythrocytes to form rosettes. The extreme variation within these proteins and the grouping of var genes implies that var gene recombination preferentially occurs within var gene groups. These groups reflect a functional diversification that has evolved to cope with the varying conditions of transmission and host immune response met by the parasite. A recombination hotspot was uncovered between Duffy-binding-like (DBL) subdomains. Solution of the crystal structure of the N-terminal and first DBL region of PfEMP1 from the VarO variant of the PfEMP1 protein is found to be directly implicated in rosetting as the heparin-binding site.

499-550 7.07e-15

Cysteine-Rich Interdomain Region 1 gamma; Rosetting is the capacity of infected RBCs to bind uninfected RBCs, which is consistently associated with severe malaria in African children. The rosette-forming PfEMP1 adhesins, namely IT4/R29, Palo Alto 89F5 VarO, 3D7/PF13_0003 and IT4/var60, belong to a specific sub-group called groupA/UpsA var genes and all four present a specific Duffy Binding-Like and and Cysteine-Rich Interdomain Region (DBL1alpha1-CIDR1gamma) double domain Head region found at the extracellular region of PfEMP1. This entry represents the CIDR1gamma domain which increases the binding affinity to VarO (Palo Alto VarO parasites).

566-706 2.56e-26

PFEMP1 DBL domain; PfEMP1 (Plasmodium falciparum erythrocyte membrane protein) has been identified as the rosetting ligand of the malaria parasite P. falciparum. Rosetting is the adhesion of infected erythrocytes with uninfected erythrocytes in the vasculature of the infected organ, and is associated with severe malaria. PfEMP1 interacts with Complement Receptor One on uninfected erythrocytes to form rosettes. The extreme variation within these proteins and the grouping of var genes implies that var gene recombination preferentially occurs within var gene groups. These groups reflect a functional diversification that has evolved to cope with the varying conditions of transmission and host immune response met by the parasite. A recombination hotspot was uncovered between Duffy-binding-like (DBL) subdomains. Solution of the crystal structure of the N-terminal and first DBL region of PfEMP1 from the VarO variant of the PfEMP1 protein is found to be directly implicated in rosetting as the heparin-binding site.

Cysteine-Rich Interdomain Region 1 gamma; Rosetting is the capacity of infected RBCs to bind uninfected RBCs, which is consistently associated with severe malaria in African children. The rosette-forming PfEMP1 adhesins, namely IT4/R29, Palo Alto 89F5 VarO, 3D7/PF13_0003 and IT4/var60, belong to a specific sub-group called groupA/UpsA var genes and all four present a specific Duffy Binding-Like and and Cysteine-Rich Interdomain Region (DBL1alpha1-CIDR1gamma) double domain Head region found at the extracellular region of PfEMP1. This entry represents the CIDR1gamma domain which increases the binding affinity to VarO (Palo Alto VarO parasites).

Duffy binding domain; This domain is found in Plasmodium Duffy binding proteins. Plasmodium vivax and Plasmodium knowlesi merozoites invade human erythrocytes that express Duffy blood group surface determinants. The Duffy receptor family is localized in micronemes, an organelle found in all organizms of the phylum Apicomplexa. This family is closely associated on PfEMP1 proteins with PFEMP, pfam03011.

566-706 2.56e-26

PFEMP1 DBL domain; PfEMP1 (Plasmodium falciparum erythrocyte membrane protein) has been identified as the rosetting ligand of the malaria parasite P. falciparum. Rosetting is the adhesion of infected erythrocytes with uninfected erythrocytes in the vasculature of the infected organ, and is associated with severe malaria. PfEMP1 interacts with Complement Receptor One on uninfected erythrocytes to form rosettes. The extreme variation within these proteins and the grouping of var genes implies that var gene recombination preferentially occurs within var gene groups. These groups reflect a functional diversification that has evolved to cope with the varying conditions of transmission and host immune response met by the parasite. A recombination hotspot was uncovered between Duffy-binding-like (DBL) subdomains. Solution of the crystal structure of the N-terminal and first DBL region of PfEMP1 from the VarO variant of the PfEMP1 protein is found to be directly implicated in rosetting as the heparin-binding site.

Duffy binding domain; This domain is found in Plasmodium Duffy binding proteins. Plasmodium vivax and Plasmodium knowlesi merozoites invade human erythrocytes that express Duffy blood group surface determinants. The Duffy receptor family is localized in micronemes, an organelle found in all organizms of the phylum Apicomplexa. This family is closely associated on PfEMP1 proteins with PFEMP, pfam03011.

Cysteine-Rich Interdomain Region 1 gamma; Rosetting is the capacity of infected RBCs to bind uninfected RBCs, which is consistently associated with severe malaria in African children. The rosette-forming PfEMP1 adhesins, namely IT4/R29, Palo Alto 89F5 VarO, 3D7/PF13_0003 and IT4/var60, belong to a specific sub-group called groupA/UpsA var genes and all four present a specific Duffy Binding-Like and and Cysteine-Rich Interdomain Region (DBL1alpha1-CIDR1gamma) double domain Head region found at the extracellular region of PfEMP1. This entry represents the CIDR1gamma domain which increases the binding affinity to VarO (Palo Alto VarO parasites).

N-terminal segments of PfEMP1; This family, the N-terminal segment, is the most variable part of the variant surface antigen family of Plasmodium falciparum, the erythrocyte membrane protein-1 (PfEMP1) proteins. PfEMP1 is an important target for protective immunity and is implicated in the pathology of malaria through its ability to adhere to host endothelial receptors. A structural and functional study of the N-terminal domain of PfEMP1 from the VarO variant comprising the N-terminal segment (NTS) and the first DBL domain (DBL1alpha1), shows this region is directly implicated in rosetting. NTS, previously thought to be a structurally independent component of PfEMP1, forms an integral part of the DBL1alpha domain that is found to be the important heparin-binding site. This family is closely associated with PFEMP, pfam03011, and Duffy_binding, pfam05424.
