ASK1 (human): Y718‑p, ASK1 iso5 (human): Y798‑p, ASK1 (mouse): Y725‑p, ASK1 (rat): Y724‑p
Upstream Regulation
Potential in vivo enzymes for site: 
Type Enzyme Evidence Notes
KINASE JAK2 (human) transfection of wild-type enzyme, phospho-antibody, activation of upstream enzyme, mutation in upstream enzyme recognition motif, co-immunoprecipitation
PHOSPHATASE SHP-2 (human) transfection of wild-type enzyme, transfection of inactive enzyme, co-immunoprecipitation
Comments:  "substrate trapping" mutant
Treatments, proteins and their effect on site modification: 
Treatments Referenced Treatments Manipulated Protein Referenced Protein Effect Notes
IFN-beta no change compared to control
TNF no change compared to control
IFN-gamma increase
IFN-gamma SOCS1 (human) no effect upon treatment-induced increase
Downstream Regulation
Effect of modification (function):  molecular association, regulation, protein degradation
Modification regulates interactions with: 
Interacting molecule Interacting domains Effect Consequences (function) Consequences (process) Detection assays
SOCS1 (human) Induces molecular association, regulation co-immunoprecipitation
Comments:  SHP2 dephosphorylation of ASK1 Y798 disrupts binding of ASK1 to SOCS1 and induces apoptosis.
