A database dedicated to the subplastidial localization of proteins

The AT_CHLORO database stores sub-plastidial (envelope, stroma, thylakoids; Ferro et al., Mol Cell Proteomics 2010; Bruley et al., Frontiers Plant Sci 2012) and sub-thylakoidal (Grana, stroma-lamellae) localization of Arabidopsis thaliana chloroplast proteins obtained from quantitative proteomics experiments as well as curated function and localization of proteins(Tomizioli et al, Mol Cell Proteomics 2014).

The AT_CHLORO database links to other public web sites (TAIR, PPDB, AtProteome, SUBA, POGs, Aramemnon)
The MASCP Gator (Joshi et al., Plant Physiol. 2011), the aggregation portal for the visualization of Arabidopsis proteomics data, gathers information from a variety of online proteomics resources including AT_CHLORO.

The AT_CHLORO database stores information for proteins that have been identified in different sub-fractions obtained from A. thaliana chloroplasts (Ferro et al., 2010).

How to use the AT_CHLORO database

Users can (i) consult the whole database, (ii) retrieve proteins that are localized in a sub-plastidial compartment (iii) or choose a set of proteins with their AGI accession numbers (Searching option).
A description of the features can be found in the help page.
