 Methods used to characterize site in vivo mutation of modification site
 Disease tissue studied:  fibrosarcoma of soft tissue
 Relevant cell lines - cell types - tissues:  293 (epithelial), COS (fibroblast), HT1080 (fibroblast)
 Cellular systems studied:  cell lines
 Species studied:  human, monkey
 Enzymes shown to modify site in vitro
Type Enzyme
KINASE PDK1 (human)
Downstream Regulation
 Effect of modification (function):  enzymatic activity, induced, molecular association, regulation
 Modification regulates interactions with: 
Interacting molecule Interacting domains Effect Consequences (function) Consequences (process) Detection assays
14-3-3 eta (human) Induces co-immunoprecipitation
14-3-3 theta (human) Induces co-immunoprecipitation, pull-down assay
 Comments:  activates PDK1 and promotes 14-3-3 binding, which inhibits PDK1 activity
