My Experience with Prediction Tools
When I first started looking into this, the TargetP-2.0 server predicts the presence of N-terminal presequences with remarkable efficiency. It is a cornerstone for anyone needing to identify signal peptides (SP), mitochondrial transit peptides (mTP), and chloroplast transit peptides (cTP). My personal experience with the tool has shown that it is a widely used server for the prediction of these sorting signals, and its transition to deep neural networks—as highlighted in "Detecting Sequence Signals in Targeting Peptides Using Deep Learning"—has significantly refined the results.
During my testing, I noticed that TargetP 1.1 predicts the subcellular location of eukaryotic proteins based on N-terminal assignments. While newer versions exist, comparing these legacy outputs against newer methods like TPpred has helped me understand the evolution of these algorithms. For those s Training and testing data set.

I am particularly impressed by the prediction of thylakoid transit peptides, which adds another layer of specificity for plant biology enthusiasts.
When I run a target sequence through these platforms, I often look for:
* Cleavage site detection: Essential for understanding how the presequence is processed.
* Organelle-specific localization: Identifying whether the peptide is destined for the mitochondria or chloroplasts.
* Structural context: Using tools like PEP-FOLD, which is a *de novo* approach aimed at predicting peptide structures, helps bridge the gap between sequence and function.
