The Tissue resource - Tissue-based map of the human proteome

This resource of the Human Protein Atlas focuses on the expression profiles in human tissues of genes both on the mRNA and protein level. The protein expression data from 44 normal human tissue types is derived from antibody-based protein profiling using conventional and multiplex immunohistochemistry. All underlying images of immunohistochemistry stained normal tissues are available together with knowledge-based annotation of protein expression levels. The protein data covers 15302 genes (76%) for which there are available antibodies. The mRNA expression data is derived from deep sequencing of RNA (RNA-seq) from 40 different normal tissue types.

More information about the specific content and the generation and analysis of the data in the resource can be found on the Methods Summary.

Learn about:

  • protein localization in tissues at a single-cell level
  • if a gene is enriched in a particular tissue (specificity)
  • which genes have a similar expression profile across tissues (expression cluster)


MULTIPLEX TISSUE PROFILINGi
Explore the proteomes of cell types and cell states

The Tissue resource has implemented a novel protocol for studying protein localization in single-cell types, cell states and subcellular structures in human tissue samples, utilizing multiplex immunohistochemistry-based fluorescence imaging. With the help of single-cell transcriptomics and an iterative staining-stripping method, seven antibody panels have been developed to profile eight different tissues. In version 24.0, 1021 proteins have been analyzed using multiplex tissue profiling. More information about the generation of the multiplex tissue profiling data can be found on the Methods page.

Based on transcriptomics analysis across all major organs and tissue types in the human body, all putative 20162 protein coding genes have been classified with regard to abundance and distribution of transcribed mRNA molecules, including 10930 proteins showing a significantly elevated level of expression in a particular tissue or a group of related tissues and 8899 proteins detected in all organs and tissues. Read more about the different categories of elevated expression here.

TISSUE EXPRESSIONi

The RNA data was used to cluster genes according to their expression across tissues. The clustering of 18492 genes expressed in tissues resulted in 83 expression clusters, which have been manually annotated to describe common features in terms of function and specificity. The result of the cluster analysis is presented as a UMAP based on gene expression, where each cluster has been summarized as colored areas containing most of the cluster genes.
