Abstract

Fasciculation and elongation zeta-1 (FEZ1) protein is involved in axon outgrowth and is highly expressed in the brain. It has multiple interaction partners, with functions varying from the regulation of neuronal development and intracellular transport mechanisms to transcription regulation. One of its interactors is retinoic acid receptor (RAR), which is activated by retinoic acid and controls many target genes and physiological process. Based on previous evidence suggesting a possible nuclear role for FEZ1, we wanted to deepen our understanding of this function by addressing the FEZ1-RAR interaction. We performed in vitro binding experiments and assessed the interface of interaction between both proteins. We found that FEZ1-RAR interacted with a similar magnitude as RAR to its responsive element DR5 and that the interaction occurred in the coiled-coil region of FEZ1 and in the ligand-binding domain of RAR. Furthermore, cellular experiments were performed in order to confirm the interaction and screen for induced target genes from an 86-gene panel. The analysis of gene expression showed that only in the presence of retinoic acid did FEZ1 induce hoxb4 gene expression. This finding is consistent with data from the literature showing the hoxb4 gene functionally involved in development and acute myeloid leukemia, as is FEZ1.
