A Protein Modification Resource

PhosphoSitePlus® (PSP) is an online systems biology resource providing comprehensive information and tools for the study of protein post-translational modifications (PTMs). In addition to providing an extensive, manually curated phosphorylation site database, other commonly studied PTMs are included in PSP. See About PhosphoSite above for more information.
