Welcome to PhosphoGRID

PhosphoGRID is an online database of experimentally verified in vivo protein phosphorylation sites in the model eukaryotic organism Saccharomyces cerevisisae. The database includes results from both high throughput (HTP) MS proteomics studies in addition to phosphosites identified in low throughput (LTP) studies of individual proteins or protein complexes. The identity of specific protein kinases and phosphatases shown to regulate appearance of phosphorylations are recorded, where available, as are the function(s) of the phosphorylation, and conditions under which the modification was demonstrated to occur. The PhosphoGRID curators would appreciate comments on omissions and errors, as well as notifications of newly published or submitted data.

  • NIH National Center for Research Resources Grant (1R01RR024031-01 to M.T. and K.D.)


PhosphoGRID search results have been permanently re-directed into the BioGRID website as our scope has expanded to cover additional post translational modifications and additional model organisms. These and ALL future efforts of our ongoing curation of post translational modifications are available online now at the BioGRID Website.
