This entry represents a domain found C-terminally to Duffy binding-like (DBL) domains of PfEMP1, the adhesin of Plasmodium falciparum which is an important target for protective immunity and is implicated in the pathology of malaria through its ability to adhere to host endothelial receptors [1-5]. This domain consists of an helical bundle.	Domain

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 [1]. 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 [2]. This family is closely associated with PFEMP, Pfam:PF03011, and Duffy_binding, Pfam:PF05424.	Domain
