Protein detail:


Protein name Matrix (M2/22K)
Uniprot protein ID P04545
Protein length 194 amino acids
Protein description Matrix (M2/22K) acts as a tetrameric transcription processivity factor that binds in a competitive manner to RNA and the phosphoprotein (P) to prevent premature termination during transcription. Transcription anti-terminator that enhances readthrough of intergenic junctions during viral transcription. Preferentially binds to poly(A)-rich sequences. Matrix (M2/22K) plays a role in the association of the matrix protein with the nucleocapsid, which initiates assembly and budding. Also, can activate host NF kappa-B through association with host RELA.

Title Targeting human respiratory syncytial virus transcription anti-termination factor M2-1 to inhibit in vivo viral replication

Evidence Genome sequencing and alignment of the supernatants revealed three coding mutations located in the hRSV M2-1 gene (Fig. 3c). While WTp was found to be identical to the original hRSV sequence, CPMR-1 and CPMR-2 consisted of a mixed population of wild-type
