USP35 binds to and deubiquitinates Aurora B, inhibiting APC/C-CDH1-mediated proteasomal degradation of Aurora B to maintain its steady-state levels during mitosis. Loss of USP35 decreases phosphorylation of histone H3-Ser10 (an Aurora B substrate) and causes mitotic defects including cytokinesis failures. FoxM1 transcription factor promotes expression of USP35 during the cell cycle. |

USP35 has two alternatively spliced isoforms with distinct intracellular localizations and functions: isoform 1 localizes to the cytoplasm/nucleus and acts as an anti-apoptotic factor inhibiting staurosporine- and TRAIL-induced apoptosis; isoform 2 is an integral membrane protein of the endoplasmic reticulum and lipid droplets, and its deregulation causes ER stress and cell death, likely through disruption of lipid homeostasis. |
