Research Abstract

We found that USP54 was phosphorylated during mitotic phase. USP54 is localized at cell-cell junction, which is dependent on an association with YWHAE protein. USP54 stabilize ZO-1 protein expression and has important role in cell-cell junction. We identified splicing variant of USP54, whose expression induced aberrant cell morphology and mitosis in glioblastoma cells.
