Regulation of Polar Auxin Transport by Protein Phosphorylation

摘要: Protein phosphorylation is one of the most important posttranslational mechanisms regulating polar auxin transport (PAT). The best known example carried out by protein kinase PINOID (PID), which determines PIN targeting at plasma membrane. PID belongs to family plant AGC kinases, play prominent roles in regulation PAT and cross talk between light-signaling pathways. Moreover, kinases belonging other families, such as CK2 or MAP are now emerging regulators recycling and/or aspects PAT, phosphoinositide biosynthetic pathway appears a significant role on trafficking. On hand, identification phosphatases that may reverse effects far behind, although rapid progress being made, providing new insights about regulation.
