Influenza Matrix protein (M1) C-terminal domain
SMART accession number:SM00759
Description: This region is thought to be a second domain of the M1 matrix protein.
Interpro abstract (IPR013188):

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. M1 is comprised of two domains connected by a linker sequence. The C-terminal domain contains alpha-helical structure and appears to be involved in growth and virulence of the virus [ (PUBMED:15892972) (PUBMED:12590584) ].

GO function:RNA binding (GO:0003723), structural molecule activity (GO:0005198)
