General annotation (Comments)

Function	Plays an important role in the cellular response to the nitrogen source. URE2 gene plays a major part in the repression of GLN1 and GDH2 genes by glutamine, and is required for the inactivation of glutamine synthetase. URE2 gene product may catalytically inactivate GLN3 in response to an increase in the intracellular concentration of glutamine.
Subunit structure	Homodimer.
Miscellaneous	Can provoque the non-Mendelian trait [URE3]. The [URE3] element of S.cerevisiae is due to the propagation of a transmissible form of the protein URE2. The infectivity of URE2 is thought to originate from a conformational change of the normal form of the prion protein. This conformational change generates a form of URE2 that assembles into amyloid fibrils. Present with 7060 molecules/cell in log phase SD medium.
Sequence similarities	Belongs to the GST superfamily. Contains 1 GST C-terminal domain. Contains 1 GST N-terminal domain.
