Science 356, eaal3321 (2017). The use of cross-linking technologies [Citation192], and cellular localization tools such as LOPPIT [Citation193] and OOPS [Citation194] are paving the way for investigating how proteins or protein complexes translocate within the cell after specific signals or perturbations or in a cell specific context.

The recent boom of the proteomics field, or the analysis of the ever dynamic organismal proteome, has brought many advances with respect to the very nature of how the current drug discovery process is undertaken. This approach has proven to be most successful for soluble proteins that retain binding competence under generic cell lysis conditions such as the E3 ligase substrate receptor CRBN as the target of thalidomide [Citation75] or Annexin A2 as a target of bleomycin in bleomycin-induced pulmonary fibrosis (PMID: 29,172,997).
