AB-loop peptide display on MS2 coat protein
Construct PatternThrough genetic engineering, antigenic peptides up to 91 amino acids in length can be densely displayed at the N-terminal β-hairpin (AB loop) of the coat protein.
Browse the toolkit beneath workflows. The mechanism branch runs mechanism -> architecture -> component, while the technique branch runs from high-level approaches down to concrete methods.

Mechanism Branch
Layer 1
Mechanisms
Top-level concepts: biophysical action modes such as heterodimerization, photocleavage, or RNA binding.
Layer 2
Architectures
Arrangements that realize or deploy mechanisms, including switches, construct patterns, and delivery strategies.
Layer 3
Components
Low-level parts and sequence-defined elements used inside architectures, including protein domains and RNA elements.
Technique Branch
Layer 1
Approaches
High-level engineering practices such as computational design, directed evolution, sequence verification, and functional assay.
Layer 2

The coat protein of the MS2 self-assembles into virus-like particles (VLPs) with a diameter of 26 nm. These VLPs are devoid of the phage genome yet are efficiently recognized by the immune system, eliciting robust humoral and cellular immune responses. The structural characteristics of VLPs position them as a promising platform for the development of vaccines and diagnostic tools.
