Protein–protein interactions are essential in various cellular processes including regulation of gene expression, formation of protein complexes, and cellular signaling transduction. In particular, several proteins in the nucleus interact to regulate transcription and RNA splicing. These protein–protein interactions are short and weak and occur through transient processes, making it difficult to identify these interactions. In addition, detection of interacting partners in vitro using cell lysates cannot provide complete information due to the loss of spatial organization and changes in protein modification. Here we describe an in vivo crosslinking technique using disuccinimidyl suberate (DSS), which is useful to capture and stabilize proteins to analyze the interacting proteins.
