Replication factor A (RPA) is a single-strand DNA binding protein involved in DNA replication, recombination and repair processes. It is composed by the subunits RPA-1, RPA-2 and RPA-3; the major DNA-binding activity resides in the subunit 1 of the heterotrimeric RPA complex. In yeast and higher eukaryotes, besides the three basic structural DNA-binding domains, the RPA-1 subunit contains an N-terminal region involved in protein-protein interactions with a fourth DNA-binding domain. Remarkably, the N-terminal extension is absent in the RPA-1 of the pathogenic protozoan Leishmania (Leishmania) amazonensis; however, the protein maintains its ability to bind ssDNA. In a recent work, we identify Leishmania (Viannia) braziliensis RPA-1 by its specific binding to the untranslated regions of the HSP70 mRNAs, suggesting that this protein might be also an RNA-binding protein.
