The E3 ubiquitin-ligase SEVEN IN ABSENTIA like 7 mono-ubiquitinates glyceraldehyde-3-phosphate dehydrogenase 1 isoform in vitro and is required for its nuclear localization in Arabidopsis thaliana

- Arabidopsis thaliana SINAL7 interacts with GAPC in vitro and modify its catalytic activity.
- SINAL7 mono-ubiquitinates GAPC in the residue K76.
- The mono-ubiquitination of GAPC, abolishes its catalytic activity.
- The presence of GAPC in the cellular nucleus is dependent on the presence of SINAL7.
