PPero, a Computational Model for Plant PTS1 Type Peroxisomal Protein Prediction
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...
متن کاملIdentification of a human PTS1 receptor docking protein directly required for peroxisomal protein import.
The discovery of many fatal human disorders resulting from impaired peroxisomal protein import makes the functional characterization of human peroxins critical. As part of our attempt to identify novel human genes and gene products involved in the import of peroxisomal proteins, we raised antisera against peroxisomal membrane proteins. One such antiserum inhibited peroxisomal protein import in ...
متن کاملPredPlantPTS1: A Web Server for the Prediction of Plant Peroxisomal Proteins
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 ...
متن کاملPTS1-independent sorting of peroxisomal matrix proteins by Pex5p.
Most peroxisomal matrix proteins contain a peroxisomal targeting signal 1 (PTS1) for sorting to the correct organelle. This signal is located at the extreme C-terminus and generally consists of only three amino acids. The PTS1 is recognized by the receptor protein Pex5p. Several examples have been reported of peroxisomal matrix proteins that are sorted to peroxisomes via Pex5p, but lack a typic...
متن کاملThe relevance of the non-canonical PTS1 of peroxisomal catalase.
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...
