Human metapneumovirus nucleoprotein (hMPV N)

The Human metapneumovirus nucleoprotein (hMPV N) is a critical structural component of the virus, responsible for encapsidating the single-stranded, negative-sense RNA genome. This encapsulation protects the viral RNA from host nucleases and serves as the essential template for both transcription and replication by the viral RNA-dependent RNA polymerase complex. The N protein forms a helical ribonucleoprotein (RNP) complex by interacting with the viral phosphoprotein (P), which acts as a bridge to the large (L) polymerase protein. Because the N protein is highly conserved and indispensable for the viral life cycle, it is a primary target for the development of antiviral therapies and vaccines. Current therapeutic strategies focus on small-molecule inhibitors that disrupt the N-P interaction or prevent N-RNA binding, as well as mRNA-based vaccines designed to elicit robust T-cell and B-cell responses against this internal viral antigen.
