GO Classification
Functions
  • glutamate-ammonia ligase activity
Processes
  • glutamine biosynthetic process
Components
  • plasma membrane
General FunctionGlutamate-ammonia ligase activity
Specific FunctionMay act as a component of the cytoskeleton or as a chaperone for the reorganization of intermediate filament proteins during terminal differentiation in the lens. Does not seem to have enzymatic activity (By similarity).
