The Subcellular Atlas

The Subcellular Atlas (also called the HPA Cell Atlas) provides high-resolution insights into the spatial distribution of proteins within cells. The protein expression data was derived from antibody-based profiling using immunofluorescence confocal microscopy. The subcellular distribution of over 12,000 proteins was classified into 30 different organelles and cellular structures. A panel of 64 cell lines was also characterized using transcriptomics. A key finding was that half of all proteins localize to multiple cellular compartments.
