Analysis of the platelet proteome. (A) Platelet proteins were detected in multiple fractions depending on the type of study. Most studies included whole platelet lysates or membrane proteome analysis. (B) Distribution of transcriptome (SAGE) and proteome proteins in the PlateletWeb database. The proteome sources were further divided into proteome studies and proteome databases with a higher fraction of proteins extracted from proteome studies. (C) Interaction, phosphorylation, and dephosphorylation events among platelet proteins are presented as fractions of the total interactome.
