Overview 
Oxidant stress-activated serine/threonine kinase that may play a role in the response to environmental stress. Targets to the Golgi apparatus where it appears to regulate protein transport events, cell adhesion, and polarity complexes important for cell migration.

Enzymatic activity 
This protein acts as an enzyme. It is known to catalyze the following reaction
EC 2.7.11.1: ATP + a protein ADP + a phosphoprotein.  
  • CuratedUniProtKB
It requires the following cofactor
Magnesium.  
  • CuratedUniProtKB
It is regulated in the following manner
Interaction with Golgi matrix protein GOLGA2 leads to autophosphorylation on Thr-174, possibly as a consequence of stabilization of dimer formation. The C-terminal non-catalytic region inhibits the kinase activity.
