DE RecName: Full=Matrix protein 2 {ECO:0000256|RuleBase:RU361247, ECO:0000256|SAAS:SAAS00395487}; GN Name=M2 {ECO:0000313|EMBL:ALR82124.1}; OS Influenza A virus (A/wild bird/Wuhan/CDHN01/2015(H11N9)). OC Viruses; ssRNA viruses; ssRNA negative-strand viruses; OC Orthomyxoviridae; Influenzavirus A. OX NCBI_TaxID=1756083 {ECO:0000313|EMBL:ALR82124.1, ECO:0000313|Proteomes:UP000115803}; RN [1] {ECO:0000313|EMBL:ALR82124.1, ECO:0000313|Proteomes:UP000115803} RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=A/wild bird/Wuhan/CDHN01/2015 {ECO:0000313|EMBL:ALR82124.1}; RA Chen L.-J., Lin X.-D., Guo W.-P., Tian J.-H., Zhang Y.-Z.; RT "Diversity and evolution of avian influenza viruses in live poultry RT markets, free range poultry and wetland regions in China."; RL Submitted (NOV-2015) to the EMBL/GenBank/DDBJ databases. CC -!- ENZYME REGULATION: The M2 protein from most influenza A strains is CC inhibited by amantadine and rimantadine, resulting in viral CC uncoating incapacity. Emergence of amantadine-resistant variants CC is usually rapid. {ECO:0000256|RuleBase:RU361247}. CC -!- SUBUNIT: Homotetramer; composed of two disulfide-linked dimers CC held together by non-covalent interactions. May interact with CC matrix protein 1. {ECO:0000256|RuleBase:RU361247}. CC -!- SUBCELLULAR LOCATION: Host apical cell membrane CC {ECO:0000256|SAAS:SAAS00581620}; Single-pass type III membrane CC protein {ECO:0000256|SAAS:SAAS00581620}. CC -!- DOMAIN: Cytoplasmic tail plays an important role in virion CC assembly and morphogenesis. {ECO:0000256|RuleBase:RU361247}. CC -!- SIMILARITY: Belongs to the influenza viruses matrix protein M2 CC family. {ECO:0000256|RuleBase:RU361247, CC ECO:0000256|SAAS:SAAS00581646}.
