RTN1-C protein is a membrane protein localized in the ER and expressed in the nervous system. Its biological role is still unclear, although interactions of the N-terminal region of RTN1-C with proteins involved in vesicle trafficking have been observed, but the role of the C-terminal region of this family protein remains to be investigated. By a homology analysis of the amino acid sequence, we identified in the C-terminal region of RTN1-C a unique consensus sequence characteristic of H4 histone protein. Thus, a 23-mer peptide (RTN1-C(CT)) corresponding to residues 186-208 of RTN1-C was synthesized, and its conformation and its interaction with nucleic acids were investigated. Here we demonstrate the strong ability of RTN1-C(CT) peptide to bind and condense the nucleic acids using electrophoretic and spectroscopic techniques. To determine if the binding of RTN1-C to nucleic acids could be regulated in vivo by an acetylation-deacetylation mechanism, as for the histone proteins, we studied the interaction of RTN1-C with one zinc-dependent histone deacetylase (HDAC) enzyme, HDAC8, with fluorescence and kinetic techniques using an acetylated form of RTN1-C(CT). The results reported here allow us to propose that the nucleic acid binding property of RTN1-C may have an important role in the biological function of this protein, the function of which could be regulated by an acetylation-deacetylation mechanism.
