abstractText | The mDaIP2 protein is a mouse orthologue of human Nostrin (a regulator of eNos). The absence of eNos activity in RA-treated F9 cell implies that the protein plays somehow different role from Nostrin. In this experiment, this protein has been shown to repress the expression of its own gene, via a feedback mechanism which involves binding to the promoter region. Data from cotransfection, DNAP, mDaIP2-silenced F9 cell, and EMSA analyses clearly support the repression activity and direct binding of the protein to the promoter region. The protein contains N-terminal FCH domain and C-terminal SH3 domain. The SH3 domain is known to interact with the proline-rich domain of mDab2, while even no function has been reported about the FCH domain. Here, we report a novel function of mDaIP2 as a transcriptional repressor and suggest the possible association of the FCH domain with transcriptional regulation. |
