Protein attributes

Sequence length	928 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Serine/threonine-protein kinase involved in the phosphorylation of the NAD+-dependent glutamate dehydrogenase GDH2. When overexpressed, confers hypersensitivity to rapamycin and induces rapid nuclear accumulation of GLN3 to activate the transcription of nitrogen-regulated genes. Ref.6 Ref.8
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Subunit structure	Interacts with URE2 and GDH2. Interacts also with the TORC1 kinase complex. Ref.8
Subcellular location	Cytoplasm Ref.4.
Sequence similarities	Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. Contains 1 protein kinase domain.
