Understand how premature stop codons interrupt protein production and why suppressor tRNA offers a new route toward restoration.
Explore the science in plain language →The molecular problem
The cell reaches “stop” too early
A nonsense mutation inserts an early stop signal into a protein-coding message. The ribosome leaves before the protein is complete, often reducing or eliminating a protein the cell needs.
The KritRNA approach
Reprogramme translation to continue
Engineered suppressor tRNAs can recognise selected premature stop codons and deliver an amino acid, allowing the ribosome to continue toward a full-length protein. The modality has already shown promise in peer-reviewed cellular and in-vivo studies. KritRNA is building the computational and experimental system needed to make that possibility precise, programmable and disease-relevant.

Design the molecule. Model the system.
KritRNA is developing two connected engines that transform a target nonsense mutation into a biologically constrained, experimentally testable suppressor tRNA shortlist.
Engine 01 · suppressor-tRNA design
Candidate generation and ranking
Sequence design, processing and identity constraints, structure and thermodynamics, kinetic context, normal-stop risk, explainable scoring and Pareto selection.
Engine 02 · translation small-world
System-level consequence modelling
A mechanistic network connecting initiation, elongation, termination, ribosome traffic, NMD, rescue, stress signalling, folding and protein output.
India-first biotechnology
Built in India. Designed for global science.

The meaning of KritRNA
Created with purpose.
Engineered to continue.
KritRNA draws its name from कृ (kṛ), the Sanskrit root meaning “to make, create or act,” and tRNA—the molecular adaptor that helps translate genetic information into protein. Together, the name means tRNA created with purpose: engineered to recognise selected premature stop codons and help translation continue toward a full-length protein.
