SHARK: web server for alignment-free homology assessment for intrinsically disordered and unalignable protein regions
(database[TitleAbstract]) AND (Nucleic acids research[Journal]) 2025-06-07
Summary:
Whereas alignment has been fundamental to sequence-based assessments of protein homology, it is ineffective for intrinsically disordered regions (IDRs) due to their lowered sequence conservation and unique sequence properties. Here, we present a web server implementation of SHARK (bio-shark.org), an alignment-free algorithm for homology classification that compares the overall amino acid composition and short regions (k-mers) shared between sequences (SHARK-scores). The output of such...
