Pf. sentrin specific protease 1 (SENP1), the thiol peptidase required for deSUMOylation and activation of SUMO precursors (SUMO is a small ubiquitin-related modifier) prior to conjugation [40], is upregulated by 5.36 ± 2.06 on day 3 post-infection by γ-irradiation. This evidence concerns the gene SENP1 and infection.
