Database Description

ExoCarta is as a free web-based resource that catalogues proteins and RNA identified in exosomes. ExoCarta is a manually curated database that contains molecular data on unpublished and published exosomal studies. It catalogs information on the exosomal isolation and purification procedures, samples used, investigator details and exosomal molecular components such as proteins, mRNA and miRNA as reported in the scientific literature. ExoCarta can be queried using the gene symbol/name or browsed as a group based on the organism, molecular content type and the sample material. Currently, ExoCarta (Version 4) contains information on 13,333 protein entries, 2,375 mRNA entries and 764 miRNA entries resulting from 146 exosomal studies. We believe that this free web-based community resource will aid researchers in identifying molecular signatures (proteins/RNA/lipids) that are specific to certain tissue/cell type derived exosomes and initiate new exosomal studies.
