Western blot - Anti-Respiratory Syncytial Virus M2-1 Protein antibody [RSV5H5] (AB94805)

RSV mutants show expected patterns of G, F, and M2-1 expression.

Western blotting of Vero cell lysates infected with RSV ΔG, ΔG C-term, and wild type (MSA1).

(Figure C shown) Detection of M2-1 using anti-M2-1 antibody ab94805.

Cell lysates from virus cultures grown for 6 days on Vero cells were subjected to SDS-PAGE, transferred to membranes and probed with anti-M2-1 antibody (Abcam, ab94805), and incubated with a secondary goat anti-mouse alkaline phosphatase conjugate. Anti-G western blot was done with rabbit anti-RSV-G polyclonal and incubated with goat anti-rabbit secondary antibody (Abcam, ab97048). Bands were visualized using BCIP/NBT. The molecular weight marker used was Precision Plus Protein Dual Color Standards.

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The Respiratory Syncytial Virus M2-1 protein also known as RSV M2-1 is an essential component in the viral replication process. This protein has a mass of approximately 19 kDa and is primarily expressed in the infected host cells. M2-1 functions as an antiterminator during viral mRNA transcription allowing the virus to produce full-length mRNA transcripts. Its role is critical for the successful synthesis of viral proteins which are necessary for virus assembly and release.
Biological function summary

The Respiratory Syncytial Virus M2-1 protein interacts with the viral RNA polymerase complex. Its activity prevents premature termination ensuring the proper transcription of viral genes. The protein plays a significant role in the synthesis of viral RNA facilitating the transition from transcription initiation to elongation. M2-1 does not act alone; it forms part of a dynamic complex with other viral proteins such as the RSV L protein and its cofactor the P protein.

Pathways

The M2-1 protein is important in the replication and transcription pathway of the Respiratory Syncytial Virus. This pathway involves other viral proteins like N (nucleoprotein) and M (matrix protein) which help stabilize and protect the viral RNA aiding in the virus's lifecycle. M2-1 regulates the switch from RNA synthesis to genome replication integrating its mechanistic functions into the larger context of viral propagation and host cell interaction.

The M2-1 protein of the Respiratory Syncytial Virus plays a central role in the pathogenesis of respiratory infections. RSV is a major cause of severe respiratory tract infections particularly in infants and the elderly causing conditions such as bronchiolitis and pneumonia. The M2-1 protein's interaction with the viral L protein during RNA synthesis can be a target for antiviral strategies aimed at disrupting the virus's replication capabilities thereby reducing disease severity.

Target data

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 (PubMed : 19386701, PubMed : 22675274). Transcription anti-terminator that enhances readthrough of intergenic junctions during viral transcription (PubMed : 10364337, PubMed : 27194388, PubMed : 8552680, PubMed : 9420254). Preferentially binds to poly(A)-rich sequences (PubMed : 24434552). Plays a role in the association of the matrix protein with the nucleocapsid, which initiates assembly and budding (PubMed : 18579594). Also, can activate host NF-kappa-B through association with host RELA (PubMed : 15629770).
