SignalP

Signal peptide prediction tool by DTU. Predicts whether a protein has a signal peptide and its cleavage site.

What It Does

  • Predicts signal peptide presence and type (Sec/SPI, Sec/SPII, Tat/SPI)
  • Cleavage site position
  • Probability scores per residue
  • Supports prokaryotes and eukaryotes

How to Use

Web

  1. Go to https://services.healthtech.dtu.dk/services/SignalP-6.0/
  2. Paste protein sequence, select Eukarya
  3. Submit and view results

Verified Status

VERIFIED — used for STRC signal peptide validation. Confirmed signal peptide in STRC N-terminus.

STRC Research Usage

  • STRC Signal Peptide Validation — confirmed SP presence and cleavage site at residue ~22
  • Important for mini-STRC design: signal peptide must be retained for ER targeting
  • E1659A is far from signal peptide (residue 1659 vs SP 1-22) — no SP effect from this variant
