[https://www.uniprot.org/uniprot/ALS9_CANAL ALS9_CANAL] Cell surface adhesion protein which mediates both yeast-to-host tissue adherence and yeast aggregation. Plays an important role in the pathogenesis of C.albicans infections (PubMed:17510860, PubMed:22321066, PubMed:22429754). Allele ALS9-2 contributes to endothelial cell adhesion, whereas ALS9-1 does not (PubMed:17600078).<ref>PMID:17510860</ref> <ref>PMID:17600078</ref> <ref>PMID:22321066</ref> <ref>PMID:22429754</ref> | |||

== Publication Abstract from PubMed == | |||
Candida albicans is the most prevalent fungal pathogen in humans and a major source of life-threatening nosocomial infections. The Als (agglutinin-like sequence) glycoproteins are an important virulence factor for this fungus and have been associated with binding of host-cell surface proteins and small peptides of random sequence, the formation of biofilms and amyloid fibers. High-resolution structures of N-terminal Als adhesins (NT-Als; up to 314 amino acids) show that ligand recognition relies on a motif capable of binding flexible C termini of peptides in extended conformation. Central to this mechanism is an invariant lysine that recognizes the C-terminal carboxylate of ligands at the end of a deep-binding cavity. In addition to several protein-peptide interactions, a network of water molecules runs parallel to one side of the ligand and contributes to the recognition of diverse peptide sequences. These data establish NT-Als adhesins as a separate family of peptide-binding proteins and an unexpected adhesion system for primary, widespread protein-protein interactions at the Candida/host-cell interface. | |||
