Distribution profiles of orthologous platelet proteins in human and mouse platelets per function class. Quantified proteins in human platelets (n = 6379) and mouse platelets (n = 4684) were assigned to 23 protein function classes. Histograms are given per class (100%) of mean copy numbers for human platelets (A) and mouse platelets (B). (C) Percentage fractions of identified proteins per class (total 100%). (D) Correlation of identified proteins per class between human and mouse platelets. Plt, platelet.
