"Dynamic SUMOylation Controls RNA Polymerase I Extranucleolar Organization and Antigenic Variation in Trypanosoma brucei"

María Agustina Berazategui, Melina Serassio, William Hack, Miguel Navarro, Joana R. Correia Faria, Paula Ana Iribarren, Vanina E. Álvarez

This paper identifies SUMOylation as a key regulator of ESB organization and antigenic variation in Trypanosoma brucei by showing its role in maintaining transcriptional compartments and VSG gene expression.

SUMO chains depolymerization induces slender to stumpy differentiation in T. brucei bloodstream parasites

Paula Ana Iribarren, Lucía Ayelén Di Marzio, María Agustina Berazategui, Andreu Saura, Lorena M. Coria, Juliana Cassataro, Federico Rojas, Miguel Navarro, Vanina E. Álvarez

This study shows that SUMO chain depolymerization is involved in the differentiation of Trypanosoma brucei from slender to stumpy forms, affecting parasitemia dynamics in mice.
