SUMO mediated regulation of transcription factors as a mechanism for transducing environmental cues into cellular signaling in plants

Roy, Dipan and Sadanandom, Ari (2021) 'SUMO mediated regulation of transcription factors as a mechanism for transducing environmental cues into cellular signaling in plants.', Cellular and molecular life sciences., 78 (6). pp. 2641-2664.


Across all species, transcription factors (TFs) are the most frequent targets of SUMOylation. The effect of SUMO conjugation on the functions of transcription factors has been extensively studied in animal systems, with over 200 transcription factors being documented to be modulated by SUMOylation. This has resulted in the establishment of a number of paradigms that seek to explain the mechanisms by which SUMO regulates transcription factor functions. For instance, SUMO has been shown to modulate TF DNA binding activity; regulate both localization as well as the abundance of TFs and also influence the association of TFs with chromatin. With transcription factors being implicated as master regulators of the cellular signalling pathways that maintain phenotypic plasticity in all organisms, in this review, we will discuss how SUMO mediated regulation of transcription factor activity facilitates molecular pathways to mount an appropriate and coherent biological response to environmental cues.
