NA-MPNN: A Deep Learning Solution for Nucleic Acid Inverse-Folding
NA-MPNN (Nucleic Acid Message Passing Neural Network), a deep learning method for predicting and designing sequences involving nucleic acids. The tool is a major advancement because it frames both RNA sequence design and protein-DNA binding specificity prediction as nucleic acid inverse-folding problems. By applying this unified inverse-folding concept, NA-MPNN provides a robust way to bridge the gap between structure and sequence in nucleic acid research.
How NA-MPNN Works
NA-MPNN uses a message-passing neural network (MPNN) architecture, a class of deep learning models that excel at modeling data structured as graphs.
Inverse Folding Framework: The model is an inverse folding tool, meaning its primary function is to take a desired 3D structure (or structural context) and predict the sequence that is most likely to fold into that shape.
Nucleic Acid Design: Specifically, it applies this inverse-folding principle to RNA sequences for design and to protein-DNA complexes for binding specificity prediction.
