The widespread occurrence of metabolically active streptomycetes in Odontotaenius disjunctus beetle frass may insulate their galleries against pathogenic fungal invasion through the production of diverse antimicrobial specialized metabolites.
A new software developed for high-throughput antibody, T cell receptor, and MHC repertoire analysis uncovers neutrality of the binding interface and intramolecular crosstalk as distinguishing properties of polyreactive antibodies.
Immunopeptidomics in combination with novel cell-based assays that assess peptide exchange reveal a critical role for the K22-D35 loop of TAPBPR in mediating peptide dissociation and peptide selection on MHC I.
The recently discovered peptide editor TAPBPR binds to UDP-glucose:glycoprotein glucosyltransferase 1 to provide quality control in the antigen presentation pathway by facilitating the reglucosylation of the glycan on MHC class I molecules.
Crystal structures of γ-protocadherin cell-cell recognition dimers reveal the determinants of clustered protocadherin homophilic specificity and cis interaction region structures alongside mutagenesis data identify the putative cis interface.
