Together with the proteasome, autophagy is one of the major catabolic pathways of the cell. In response to cellular needs or environmental cues, this transport route targets specific structures for degradation into the mammalian lysosomes or the yeast and plant vacuoles. The mechanisms allowing exclusive autophagic elimination of unwanted structures are currently the object of intensive investi...
Here we report a method for efficient transfection of in vitro-transcribed mRNA into two different types of human adherent cells, the neuroblastoma cell line SK-N-AS, and the transformed kidney cell line HEK293. By using newly trypsinized adherent cells in suspension and Lipofectaminetrade mark 2000, we detected a transfection efficiency of 80-90% in both cell lines and a cell viability of 90% ...
We demonstrate that the peroxin Pex3 is not required for the formation of peroxisomal membrane structures in yeast pex3 mutant cells. Notably, pex3 mutant cells already contain reticular and vesicular structures that harbor key proteins of the peroxisomal receptor docking complex-Pex13 and Pex14-as well as the matrix proteins Pex8 and alcohol oxidase. Other peroxisomal membrane proteins in thes...
This contribution describes the phenotypic differences of yeast peroxisome-deficient mutants (pex mutants). In some cases different phenotypes were reported for yeast mutants deleted in the same PEX gene. These differences are most likely related to the marker proteins and methods used to detect peroxisomal remnants. This is especially evident for pex3 and pex19 mutants, where the localization ...
PEX13 is an integral membrane protein on the peroxisome that regulates peroxisomal matrix protein import during peroxisome biogenesis. Mutations in PEX13 and other peroxin proteins are associated with Zellweger syndrome spectrum (ZSS) disorders, a subtype of peroxisome biogenesis disorder characterized by prominent neurological, hepatic, and renal abnormalities leading to neonatal death. The la...
Pex1 and Pex6 are two AAA-ATPases that play a crucial role in peroxisome biogenesis. We have characterized the ultrastructure of the Saccharomyces cerevisiae peroxisome-deficient mutants pex1 and pex6 by various high-resolution electron microscopy techniques. We observed that the cells contained peroxisomal membrane remnants, which in ultrathin cross sections generally appeared as double membra...
Peroxisomes, chloroplasts, and mitochondria are essential eukaryotic organelles that host a suite of metabolic processes crucial to energy metabolism and development. Regulatory mechanisms of the dynamics and biogenesis of these important organelles have begun to be discovered in plants. We recently showed that, aside from its previously reported role in targeting chloroplast protein import pro...
