Influenza matrix M1, N-terminal (IPR001561)

Short name: Flu_matrix_M1_N

Overlapping homologous superfamilies

Domain relationships



Matrix protein (M1) of influenza virus is a bifunctional membrane/RNA-binding protein that mediates the encapsidation of RNA-nucleoprotein cores into the membrane envelope. It is therefore required that M1 binds both membrane and RNA simultaneously [PMID: 9164466]. M1 is comprised of two domains connected by a linker sequence. The N-terminal domain has a multi-helical structure that can be divided into two subdomains [PMID: 11162800]. The C-terminal domain also contains an alpha-helical structure.
