Posttranslational Modification

Posttranslational Modification	Comment	Organism
phosphoprotein	phosphorylation/dephosphorylation of ACS2 regulates its turnover upstream of the ubiquitin-26S-proteasome degradation pathway. ACS2 is stabilized by phosphorylation and degraded after dephosphorylation. The amount of ACS2 affected by the protein kinase/phosphatase inhibitors significantly influences cellular ACS activity, 1-aminocyclopropane-1-carboxylic acid content, and ethylene production levels in tomato fruit tissue. Calcium-dependent protein kinase CDPK2, is one of the protein kinases that are able to phosphorylate ACS2 at residue S460. ACS2 is immediately phosphorylated after translation by CDPK and mitogen-activated protein kinase at different sites in response to wound signaling and almost all functional ACS2 molecules are phosphorylated in the cell. Phosphorylation at both sites is required for ACS2 stability	Solanum lycopersicum
