    basic FUNCTION
  • first step in the synthesis of phosphotidylinositol 4-J biphosphate
  • does not play a significant role in the vulnerability to METH use disorder (Kanahara 2009)
  • host factor essential for hepatitis C virus replication and hence is a target for drug development
  • is essential for the maintenance of plasma membrane phosphatidylinositol 4,5-bisphosphate pools but only during strong stimulation of receptors coupled to phospholipase C activation
  • role for PI4KA in myelin formation primarily affecting metabolism of key phospholipids and the actin cytoskeleton
