As you were figuring out hiw the PUR-mediated signaling pathway works in P. microspora., perhaps in some cases it wasn't clear how certain proteins were being activated or inactivated, or what certain proteins might be doing. Identify each case where insufficient information was provided to understand a protein's contribution or regulation. Choose one of the cases you identified and propose an experiment (including appropriate controls) that might enable us to better understand how that protein functions in this signaling pathway or how it is turned on/off?o
