TIGR-Tas: The Compact Gene-Editing Pioneer of 2025

1. Compact & versatile: At about one-quarter the size of Cas9, TIGR‑Tas systems are easier to deliver into cells—especially important for therapeutic contexts where payload size matters Wikipédia+1.
2. Dual‑spacer targeting: Unlike CRISPR systems that rely on a single guide RNA and PAM sequences, TIGR‑Tas employs two spacers that must accurately bind both DNA strands—boosting specificity and target versatility without needing PAM sequences Wikipédia+1.
3. Modular components: Researchers identified types like TasA, TasH, and TasR—each integrating different functional domains (e.g., nucleases)—opening up adaptable use cases Wikipédia+1.

Why 2025 Feels Like a Turning Point
