The cell surface proteome, or surfaceome, is the hub for cells to interact and communicate with outside world. Many disease-associated changes are hard-wired within yet approved drugs target less than 50 proteins. In past decade, proteomics community has made significant strides in developing new technologies tailored studying surfaceome all its complexity. this review, we first dive into unique characteristics functions of emphasizing necessity specialized labeling, enrichment, proteomic approaches. An overview surfaceomics methods provided, detailing techniques measure protein expression how leads novel discovery. Next, highlight advances proximity labeling (PLP), showcasing various enzymatic photoaffinity can map protein-protein interactions membrane complexes on surface. We then review role extracellular post-translational modifications, focusing glycosylation, proteolytic remodeling, secretome. Finally, discuss identifying tumor-specific peptide MHC they have shaped therapeutic development. This emerging field neo-protein epitopes constantly evolving, where targets identified at proteome level encompass defined PTMs, complexes, dysregulated cellular tissue locations. Given functional importance biology therapy, view as a critical piece quest neo-epitope
