Chromosome {ECO:0000269|PubMed:17185418}. Cytoplasm {ECO:0000269|PubMed:32272059}. Cytoplasmic vesicle, secretory vesicle {ECO:0000269|PubMed:22215666}. Secreted {ECO:0000269|PubMed:19465481}. Note=Associates with heterochromatin and mitotic chromosomes (PubMed:17185418). The secretion is dependent on protein unfolding and facilitated by the cargo receptor TMED10;
it results in protein translocation from the cytoplasm into the ERGIC (endoplasmic reticulum-Golgi intermediate compartment) followed by vesicle entry and secretion (PubMed:32272059). {ECO:0000269|PubMed:32272059}.
