Matrix 1/M1, H1N1 (NP_040978, His)

Matrix protein 1/M1 Protein is pivotal in virus replication, spanning entry, uncoating, assembly, and budding. Binding to ribonucleocapsids inhibits viral transcription, and interaction with NEP aids nuclear export. M1 forms a shell on the inner virion membrane, binding the RNP. During entry, M1 dissociates from the RNP, allowing nuclear transport for transcription. M1 influences virion shape, determining infectivity, with filamentous virions crucial for cell-to-cell spread and spherical virions for aerosol-based transmission. Matrix protein 1/M1 Protein, H1N1 (NP_040978, His) is the recombinant Virus-derived Matrix protein 1/M1 protein, expressed by E. coli , with N-His labeled tag.
