Influenza A Matrix Protein 1 (M1)

Target
M1
Molecular classification
Structural protein, Matrix protein
01

Overview

Influenza A matrix protein 1 (M1) is a multifunctional structural component essential for influenza virus replication. It orchestrates key steps such as particle assembly/budding by forming an endoskeletal layer under the lipid envelope while mediating interactions among various viral components—including glycoproteins on the surface and internal ribonucleoproteins—and regulating processes like nuclear export through post-translational modifications such as phosphorylation. Its highly ordered structure makes it vital not only to virion stability but also to potential antiviral strategies targeting its unique interfaces or regulatory mechanisms.
