Visual Inventory of Surface N-Glycoproteins (VISUN)
Our catalog of experimentally verified surface proteins from >150 cell types/lines currently contains >2700 proteins and is housed in an SQL database on a secure server in the Gundry lab termed the Visual Inventory of Surface N-glycoproteins (VISUN (pronounced vision)). While a subset of these data is collated in the Cell Surface Protein Atlas, an additional 60+ unpublished cell types remain unique to VISUN. Accessing the VISUN repository provides a rapid and unique strategy to identify proteins that are ubiquitously expressed among a wide range of cell types, as well as those more restricted to a specific cell type or lineage. Although the failure to identify a protein by CSC is not conclusive evidence of the protein’s absence in a cell type, nor has every cell type yet been mapped, these comparisons are rapid first steps to narrow down preliminary targets for next level validation.
