Witryna15 cze 2008 · Both the steady-state levels of Fis1 and its in vitro insertion into isolated mitochondria were unaffected when mitochondria mutated in known import factors were analyzed. Fis1 was inserted into lipid vesicles, and importantly, elevated ergosterol contents in these vesicles inhibited this insertion. Witrynadria requires the import not only of proteins from the cytoplasm but also of lipids from extramitochondrial membranes as mitochondria cannot synthesize all the lipids necessary for membrane biogenesis.
