Cellular localization
Nucleus . Cytoplasm . Chromosome . Endoplasmic reticulum . Cytoplasm, perinuclear region . Cytoplasmic vesicle, autophagosome . Colocalizes with the proteasome, both in nucleus and cytoplasm (PubMed:15280365). Exported from the nucleus following interaction with DESI1/POST (PubMed:29666234). In response to DNA damage and phosphorylation at Ser-318 by ATM, localizes to the nucleus and is recruited to sites of DNA damage (PubMed:30612738). .
Tissue expression
Highly expressed in pancreas, kidney, skeletal muscle, heart and throughout the brain, and at lower levels in placenta, lung and liver.
