Abstract

Using #fluorescentproteins as imaging probes is a wide spread and versatile technique in #microscopy. GFP tagged proteins can be used to track and examine real time localization, interactions and translocation of proteins of interest as well as to investigate several aspects of cell biology. The Y-box binding protein 1 (YB-1) is a pleiotropic protein involved in a widenumber of #cellularprocesses and a substantial amount of knowledge on YB-1 localization and function was produced using YB-1-GFP constructs. Recently, it has been shown that YB-1 plays a critical role in cell stress response, playing an important role in the formation of #stressgranules (SG). To deeply investigate on this subject, we produced a stable HEK293T cell line constitutively expressing YB-1-GFP. In physiological conditions YB-1-GFP expressing cells behaved like the parental cells and YB-1-GFP protein properly localized to the #cytoplasmiccompartment.
