Welcome to SEPPA 3.0 !

spatial epitope prediction for protein antigens, particularly for N-linked glycoproteins

SEPPA 3.0 is an enhanced version of SEPPA2.0. In this latest version, SEPPA 3.0 realized below functions: 1) Improved the performance on common protein antigens by updating the training dataset; 2) Incorporated new features enabling the accurate prediction for N-linked glycoprotein antigens. As the first algorithm considering the N-glycosylation sites, SEPPA 3.0 shows significant advantages over popular peers both on common and N-linked glycoprotein antigens. More information can be found in help page of SEPPA3.0.

Example of SEPPA 3.0 predictions (PDB ID: 5IF0), the left one represents reference epitope residues marked in red, the right one displays the predicted epitope marked with RPG (Red-salmon-Pink-white-Grey) gradient, while tints from grey to red shows the rising of antigenicity score.
