摘要: Leucine-rich repeats (LRRs) are versatile motifs present in more than 6000 proteins throughout the phylogenetic kingdom. Tandem LRRs generate a characteristic horseshoe with diverse range of functions. Fulfilling key role innate immune system, form TLR and NOD-like receptor (NLR) pathogen-recognition domain. Host–pathogen interactions mediated by drive those involved ligand recognition to become distinct from their consensus motif. Most between 21 30 residues; however, large insertions certain TLRs can over 60 amino acids. LRR variability makes them ideal for species-specific mediation host-pathogen interactions. Teleost show insertions, making cross-species alignments difficult without prior demarcation motifs. We LRRfinder2.0, webserver prediction. LRRfinder2.0 utilizes scoring matrices comprising 60,000 200 species. The underlying database tLRRdb contain...
