  • Title: Protocol for affinity purification-mass spectrometry interactome profiling in larvae of Drosophila melanogaster.
    Author: Guo Y, Hartson SD, Rogers J, Brooks-Kanost L, Brooks D, Geisbrecht ER.
    Journal: STAR Protoc; 2024 Jun 21; 5(2):103064. PubMed ID: 38743568.
    Abstract:
    Many techniques exist for the identification of protein interaction networks. We present a protocol that relies on an affinity purification-mass spectrometry (AP-MS) approach to detect proteins that co-purify with a tagged bait of interest from Drosophila melanogaster larval muscles using the GAL4/upstream activating sequence (UAS) expression system. We also describe steps for the isolation and identification of protein complexes, followed by streamlined bioinformatics analysis for rapid and reproducible results. This protocol can be extended to investigate protein interactions in other tissues. For complete details on the use and execution of this protocol, please refer to Guo et al.1.
