Subcellular location [CC]Nucleus. Cytoplasm. Membrane {ECO:0000250}. Mitochondrion. Note=A small fraction localizes at membranes (By similarity). Relocates to the cytoplasm when bound to STRAD (STRADA or STRADB) and CAB39/MO25 (CAB39/MO25alpha or CAB39L/MO25beta). Translocates to the mitochondrion during apoptosis. PTEN promotes cytoplasmic localization. {ECO:0000250}.;
[Isoform 2]: Nucleus {ECO:0000269|PubMed:23612973}. Cytoplasm {ECO:0000269|PubMed:23612973}. Note=Predominantly nuclear, but translocates to the cytoplasm in response to metformin or peroxynitrite treatment.
