Subcellular location [CC]Nucleus {ECO:0000269|PubMed:10393201}. Cytoplasm, cytosol {ECO:0000269|PubMed:16818237}. Endoplasmic reticulum membrane {ECO:0000269|PubMed:33476576};
Peripheral membrane protein {ECO:0000269|PubMed:33476576}. Note=Retained in the cytoplasm through the C-terminal region (By similarity). Localization to the endoplasmic reticulum membrane is required to direct TREX1 to ruptured micronuclei (PubMed:33476576). In response to DNA damage, translocates to the nucleus where it is specifically recruited to replication foci (PubMed:16818237). Translocation to the nucleus also occurs during GZMA-mediated cell death (PubMed:16818237). {ECO:0000250|UniProtKB:Q91XB0, ECO:0000269|PubMed:16818237, ECO:0000269|PubMed:33476576}.
