چکیده انگلیسی
Protein maturation in eukaryotic organelles requires the type I chaperonin system; this comprises chaperonin 60 (Cpn60) and its cochaperonin. We have re-examined and revised the sequence of the nuclear genes specifying organellar cochaperonins in Plasmodium falciparum (Pf). One gene encodes a typical cochaperonin (PfCpn10) whereas the other (encoding PfCpn20) specifies two Cpn10 domains arranged in tandem as in plant chloroplasts. Transfection experiments using fluorescent reporters showed specific localization of PfCpn10 to the mitochondrion and PfCpn20 to the plastid. As P. falciparum also has two Cpn60s, one of which is targeted specifically to the mitochondrion and the other exclusively to the plastid, each organelle has a distinct type I chaperonin system. Comparative sequence analysis extended these findings to several other apicomplexan parasites that have both a mitochondrion and a plastid. Phylogenetic analysis suggests the Cpn10s and Cpn20s of apicomplexans are independently monophyletic. The apicomplexan Cpn10 is phylogenetically related to other mitochondrial versions but a significant relationship between apicomplexan Cpn20s and other cochaperonins was not established.
