Well-defined motifs often make it easy to investigate protein function and localization. In plants, peroxisomal proteins are guided to peroxisomes mainly by a conserved type 1 (PTS1) or type 2 (PTS2) targeting signal, and the PTS1 motif is commonly used for peroxisome targeting protein prediction. Currently computational prediction of peroxisome targeted PTS1-type proteins are mostly based on t...

Translational readthrough gives rise to low abundance proteins with C-terminal extensions beyond the stop codon. To identify functional translational readthrough, we estimated the readthrough propensity (RTP) of all stop codon contexts of the human genome by a new regression model in silico, identified a nucleotide consensus motif for high RTP by using this model, and analyzed all readthrough e...

The peroxisome targeting signal type 1 (PTS1) receptor, Pex5p, of the tetratricopeptide repeat (TPR) motif family is located mostly in the cytosol and mediates the translocation of PTS1 proteins to peroxisomes. As a step towards understanding the mechanisms of protein import into peroxisomes, we investigated the molecular mechanisms involved in PTS1 recognition by Pex5p with regard to requireme...

We previously described the isolation of mutants of the yeast Pichia pastoris that are deficient in peroxisome assembly (pas mutants). We describe the characterization of one of these mutants, pas8, and the cloning of the PAS8 gene. The pas8 mutant is deficient for growth, but not for division or segregation of peroxisomes, or for induction of peroxisomal proteins. Two distinct peroxisomal targ...

Prediction of subcellular protein localization is essential to correctly assign unknown proteins to cell organelle-specific protein networks and to ultimately determine protein function. For metazoa, several computational approaches have been developed in the past decade to predict peroxisomal proteins carrying the peroxisome targeting signal type 1 (PTS1). However, plant-specific PTS1 protein ...

Background: Some resources have suggested that genetically inactivated pertussis toxoid (PTs) bear a more protective effect than chemically inactivated products. This study aimed to produce new version of PT, by cloning an inactive pertussis toxin S1 subunit (PTS1) in a fusion form with N-terminal half of the listeriolysin O (LLO) pore-forming toxin. Methods: Deposited pdb structure file of the...

Acyl-CoA oxidase (Pox1p) is involved in the beta-oxidation of fatty acids and is targeted to the peroxisomal matrix via the use of different signals in various organisms. In rat, mouse and human, Pox1p contains a canonical peroxisomal targeting signal 1 (PTS1), whereas in the yeasts Candida tropicalis, Saccharomyces cerevisiae, C. maltosa and Yarrowia lipolytica neither a PTS1 nor a PTS2 sequen...

Catalase is sorted to peroxisomes via a C-terminal peroxisomal targeting signal 1 (PTS1), which binds to the receptor protein Pex5. Analysis of the C-terminal sequences of peroxisomal catalases from various species indicated that catalase never contains the typical C-terminal PTS1 tripeptide-SKL, but invariably is sorted to peroxisomes via a non-canonical sorting sequence. We analyzed the relev...

In its role as a mobile receptor for peroxisomal matrix cargo containing a peroxisomal targeting signal called PTS1, the protein Pex5 shuttles between the cytosol and the peroxisome lumen. Pex5 binds PTS1 proteins in the cytosol via its C-terminal tetratricopeptide domains and delivers them to the peroxisome lumen, where the receptor·cargo complex dissociates. The cargo-free receptor is exporte...

We have identified an S. cerevisiae integral peroxisomal membrane protein of M of 42,705 (Pex13p) that is a component of the peroxisomal protein import apparatus. Pex13p's most striking feature is an src homology 3 (SH3) domain that interacts directly with yeast Pex5p (former Pas10p), the recognition factor for the COOH-terminal tripeptide signal sequence (PTS1), but not with Pex7p (former Pas7...
