The binding is not specific to any RNA sequence, and is performed via a peptide sequence rich in base chemistry basic amino acid s. It also has multiple regulatory functions, performed by interaction with the components of the host cell. The mechanisms regulated include a role in the export of the viral ribonucleoprotein s from the host cell nucleus , inhibition of viral transcription genetics transcription , and a role in the virus assembly and budding . The protein was found to undergo phosphorylation in the host cell.
