Tysnd1 Deficiency in Mice Interferes with the Peroxisomal Localization of PTS2 Enzymes, Causing Lipid Metabolic Abnormalities and Male Infertility
Peroxisomes are subcellular organelles involved in lipid metabolic processes, including those of very-long-chain fatty acids and branched-chain fatty acids, among others. Peroxisome matrix proteins are synthesized in the cytoplasm. Targeting signals (PTS or peroxisomal targeting signal) at the C-terminus (PTS1) or N-terminus (PTS2) of peroxisomal matrix proteins mediate their import into the or...
متن کاملIdentification of the peroxisomal β-oxidation enzymes involved in the degradation of long-chain dicarboxylic acids
Dicarboxylic acids (DCAs) are -oxidation products of monocarboxylic acids. After activation by a dicarboxylyl-CoA synthetase, the dicarboxylyl-CoA esters are shortened via -oxidation. Although it has been studied extensively where this -oxidation process takes place, the intracellular site of DCA oxidation has remained controversial. Making use of fibroblasts from patients with defined mitochon...
متن کاملDeg Proteases in Arabidopsis thaliana
Two distinct peroxisomal targeting signals (PTSs), the C-terminal PTS1 and the N-terminal PTS2, are defined. Processing of the PTS2 on protein import is conserved in higher eukaryotes. Recently, candidates for the responsible processing protease were identified from plants (DEG15) and mammals (TYSND1). We demonstrate that plants lacking DEG15 show an expressed phenotype potentially linked to re...
