Zusammenfassung:The present application is related to a modified protein comprising a protein having a coiled coil domain and a peptide having the sequence such as shown in SEQ ID NO 1: ZXBBBBZ that is linked to the coiled coil domain wherein: • Z is any amino acid or is absent; • X is any amino acid; • B is an arginine (R) or a lysine (K). Said modified protein is in particular an antigen or a carrier protein, associated to an antigen. This modified protein has an increased affinity for negatively charged polymers such as nucleic acids or heparin, and shows an increased immunogenicity. La solicitud presente se relaciona a una proteína modificada que comprende una proteína que tiene un dominio de espiral enrollada y un péptido que tienen la secuencia como se muestra en SEQ ID NO: 1: ZXBBBBZ que se enlaza al dominio de espiral enrollada en donde: • Z es cualquier aminoácido o está ausente; • X es cualquier aminoácido; • B es una arginina (R) o una lisina (K); dicha proteína modificada es en particular un antígeno o una proteína de portador, asociada a un antígeno; esta proteína modificada tiene una afinidad aumentada para polímeros con carga negativa tales como ácidos nucleicos o heparina, y muestra un aumento de inmunogenicidad.
