Multiple Sequence Alignment
A bioinformatics method that aligns multiple homologous protein sequences to extract conserved residues and covariation signals, which are used to infer spatial contact relationships and structural features.
Timeline (last 90 days)
AlphaFold relies on evolutionary information (multiple sequence alignments) in known structure databases, and what it learns is a statistical mapping from sequence to structure, rather than the physical mechanism of folding.
When the target protein lacks enough homologous sequences (such as orphan proteins, artificially designed proteins, or certain viral proteins), MSA information is sparse, and AlphaFold's prediction accuracy drops明显.
