dc.description.abstract | The deubiquitinase USP21 shuttles between the nucleus and the cytoplasm and can also localize to the centrosome, but how this complex subcellular localization is modulated remains unknown. A proteomics analysis has identified the centrosomal kinase MARK4 as a potential USP21-interacting partner. In this work, we validate the USP21/MARK4 interaction, identifying the MARK4-binding region of USP21. Our results indicate that MARK4 interaction may regulate USP21 nucleocytoplasmic shuttling dynamics, increasing its retention in the cytoplasm. On the other hand, our data show that the centrosomal localization of both proteins is highly dynamic, and suggest that USP21 centrosomal dynamics might be modulated by MARK4.; USP21 deubikuitinasa nukleoaren eta zitoplasmaren artean translokatzen da, eta zentrosoman ere koka daiteke, baina kokapen azpizelular konplexu hori nola modulatzen den ezezaguna da. Proteomika-analisiaren bidez, MARk4 kinasa zentrosomala identifikatu da USP21 proteinaren balizko interaktore gisa. Lan honetan, USP21/MARk4 interakzioa balioztatzen dugu, eta USP21 proteinan MARk4 lotura-eskualdea identifikatu. Gure emaitzen arabera, MARk4ekiko interakzioak USP21en nukleoaren eta zitoplasmaren arteko kokapen dinamikoa erregula dezake, zitoplasmarekiko atxikipena areagotuz. Bestalde, gure datuek bi proteinen kokapen zentrosomala oso dinamikoa dela erakusten dute, eta USP21en dinamika zentrosomala MARk4en bidez modula daitekeela iradokitzen dute. | |
