PhosphoSitePlus

A Protein Modification Resource

Protein Sequences

PhosphoSitePlus^® (PSP) is an online systems biology resource providing comprehensive information and tools for the study of protein post-translational modifications (PTMs). See About PhosphoSite above for more information.

PROTEIN OR SUBSTRATE SEARCH

ADVANCED SEARCH AND BROWSE OPTIONS

	Protein, Sequence, or Reference Search Protein, Sequence, or Reference Search: Protein Searches retrieve lists of proteins and their modification types based on protein name or ID, protein type, domain, cellular component, and MW range. Sequence searches retrieve lists of proteins and sequences containing specified sequences, degenerate motifs, and domains. Reference searches retrieve lists of literature references specified by authors, proteins, or PubMedIDs.
	Site Search Site Search: Retrieves a list of modified sites (with surrounding amino-acid sequence) and proteins from which they come. Searches can be restricted by eight criteria: sites responsive to specific treatments, or those observed in specific protein types, domains, cellular components, disease states, cell lines, cell types, or tissues.
	Comparative Site Search Comparative Site Search: Retrieves a list of modified sites that possess certain specified attributes and exclude others. Searches can be restricted by the same eight properties as for the "Site Search".
	Browse MS2 Data By Disease Browse MS2 Data By Disease: Allows the user to browse curated MS/MS records by selecting a disease type. Results show the number of records and associated modification sites observed in the selected disease.
	Browse MS2 Data by Cell Line Browse MS2 Data by Cell Line: Allows the user to browse curated MS/MS records by selecting a cell line. Results show the number of records and associated modification sites observed in the selected cell line.
	Browse MS2 Data by Tissue Browse MS2 Data by Tissue: Allows the user to browse curated MS/MS records by selecting a tissue. Results show the number of records and associated modification sites observed in the selected tissue.
