DEPDC1 physically interacts with the zinc finger transcription factor ZNF224 (a transcriptional repressor) in bladder cancer cells; this complex suppresses transcription of A20, an NF-κB inhibitor. Disrupting the DEPDC1-ZNF224 interaction with a cell-permeable peptide triggers A20 transcriptional activation and induces apoptosis in vitro and in vivo. |

In C. elegans, the DEPDC1 ortholog LET-99 acts upstream of the heterotrimeric G-protein alpha subunit GPA-11 to control activation of the stress kinase JNK-1 in the anti-tubulin drug-induced apoptosis pathway. Human DEPDC1 similarly promotes vincristine-induced cell death via JNK-dependent degradation of the BCL-2 family protein MCL1. |

DEPDC1 isoform a localizes to the centrosome in metaphase (while isoform b localizes to the cell cortex during mitosis); phosphorylation of DEPDC1 at Ser110 is required for centrosomal localization of isoform a and for maintenance of centrosome integrity and bipolar spindle organization. Non-phosphorylatable mutants of DEPDC1a fail to rescue centrosome disruption caused by endogenous DEPDC1 depletion. |
