Description
Plasmodium falciparum, the main agent of malaria expresses six members of the heat shock protein 70 (Hsp70) family. Hsp70s serve as protein folding facilitators in the cell. Amongst the six Hsp70 species that P. falciparum expresses, Hsp70‐x (PfHsp70‐x), is partially exported to the host red blood cell where it is implicated in host cell remodeling. Nearly 500 proteins of parasitic origin are exported to the parasite‐infected red blood cell (RBC) along with PfHsp70‐x. The role of PfHsp70‐x in the infected human RBC remains largely unclear. One of the defining features of PfHsp70‐x is the presence of EEVN residues at its C‐terminus. In this regard, PfHsp70‐x resembles canonical eukaryotic cytosol‐localized Hsp70s which possess EEVD residues at their C‐termini in place of the EEVN residues associated with PfHsp70‐x. The EEVD residues of eukaryotic Hsp70s facilitate their interaction with co‐chaperones …
