Nipah virus (NiV) was identified in Malaysia in 1998 as the etiological agent of an outbreak of acute encephalitis with high mortality. The L gene of NiV encodes the RNA-dependent RNA polymerase required for replication. This study investigates the role of the N-terminal domain of the L protein through deletion mutagenesis and a minigenome assay system. Five N-terminal deletions were introduced and tested for function using a minigenome system encoding a CAT reporter. Results show that the first 100 amino acids of the L protein are essential for transcription and possibly phosphoprotein interaction. These findings highlight the importance of the NH2-terminal domain in transcription and provide a foundation for antiviral strategies targeting this domain.
