AUP1 May play a role in the translocation of terminally misfolded proteins from the endoplasmic reticulum lumen to the cytoplasm and their degradation by the proteasome. Belongs to the AUP1 family. Detected in blood platelets and leukocytes (at protein level). Ubiquitous. Highly expressed in placenta, liver, kidney, skeletal muscle, heart and brain. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
