Proteins of the stomatin/prohibitin/flotillin/HfIK/C (SPFH) family are membrane-anchored and perform diverse cellular functions in different organelles. A systematic database search for Plasmodium SPFH proteins uncovered four candidates that either display a close phylogenetic relationship to conserved members—prohibitin 1 (PHB1, PBANKA_0701500), prohibitin 2 (PHB2, PBANKA_1213100), and stomatin-like protein (STOML, PBANKA_0807100)- 0807100)—or fall into a unique sister group that contains related proteins from the phylum Myzozoa, which harbors the subphylum Apicomplexa. Accordingly, the latter Plasmodium protein was named prohibitin-like protein (PHBL, PBANKA_0718600). All four proteins contain a central signature SPFH domain and a hydrophobic stretch Although the conventional Plasmodium SPFH proteins display a similarly high degree of conservation, PHBL sequences are rather divergent already among related Plasmodium species.
