Protein Classification

PRESAN domain-containing protein( domain architecture ID 10560507)

PRESAN (Plasmodium RESA N-terminal) domain-containing protein, similar to Plasmodium falciparum PHIST protein that binds the virulence factor PfEMP1 and comigrates to knobs on the host cell surface

Plasmodium RESA N-terminal; The short, four-helical domain first identified in the Plasmodium export proteins PHISTa and PHISTc has been extended to become this six-helical PRESAN domain identified in the P. falciparum-specific RESA-type (Ring-infected erythrocyte surface antigen) proteins in association with the DnaJ domain. Overall, at least 67 proteins have been detected in P. falciparum with complete copies of the PRESAN domain. No versions of this domain were detected in other apicomplexan genera, suggesting that the domain was 'invented' after the divergence of the lineage leading to the genus Plasmodium undergoing a dramatic proliferation only in P. falciparum. A secondary structure-prediction derived from the multiple alignment of the PRESAN family reveals that it is composed of an all-helical fold with six conserved helical segments. There is some evidence it might localize to membranes.

Plasmodium falciparum uncharacterized domain TIGR01639; This model represents a conserved sequence region of about 60 amino acids found in over 40 predicted proteins of Plasmodium falciparum. It is not found elsewhere, including closely related species such as Plasmodium yoelii. No member of this family is characterized.
