STRC Web Prediction Jobs (2026-03-19)

Submitted Jobs

All three sequences submitted to each tool:

  1. full_STRC (1775 aa) — positive control
  2. IgK_SP_shorter_mini_STRC (1097 aa) — our construct
  3. shorter_mini_STRC_no_SP (1076 aa) — negative control

SignalP 6.0 — COMPLETE ✅

Results: see STRC Signal Peptide Validation

NetGPI 1.1 — COMPLETE ✅

Key: mini-STRC lipid anchor 72.1% vs full STRC 28.4%. Truncation makes GPI signal more prominent.

NetNGlyc 1.0 — COMPLETE ✅

Job ID: 69BB95040023E1E80CE6DABF

Full STRC: 14 NxS/T sequons, 13 predicted glycosylated (threshold 0.5)

  • Strongest: N65 NISS 0.757 (9/9), N476 NETL 0.707 (9/9), N565 NDTC 0.619 (9/9)
  • Below threshold: N824 NDSV 0.452 (4/9)
  • N696 NPSS in cut zone has PRO-X1 warning

IgK + mini-STRC: 5 sequons, ALL glycosylated ✅
