检测与应用COMPOSITIONS AND METHODS FOR DETECTING NUCLEIC ACID-PROTEIN ...2022-08-25US202217822418Compositions and methods for detecting nucleic acid-protein interactions, or more generally interactions between a nucleic acid and another molecule. A Cas protein (e.g., a catalytically dead Cas13) is fused to a proximity tagging enzyme (e.g., a Pup ligase) and thus brings the proximity tagging enzyme to the proximity of a protein that binds to a nucleic acid, when the Cas protein recognizes the nucleic acid, e.g., through a guide RNA. The proximity tagging enzyme then tags the protein enabling it to be identified as a protein that interacts with the nucleic acid.[详情]

检测与应用COMPOSITIONS AND METHODS FOR DETECTING MOLECULE-MOLECULE INT...2022-09-07US17930401Compositions and methods for detecting molecule-molecule interactions are provided. The methods employ a prokaryotic ubiquitin-like protein (Pup) and a Pup ligase that is coupled to one of the molecules. When the Pup ligase is brought to proximity to the other molecule by virtue of the molecule-molecule interaction, the Pup ligase can conjugate the Pup to a lysine residue on the other molecule. As such conjugation can be easily detected, this method allows easy identification of the molecule-molecule interaction.[详情]
