M2-2 protein of human respiratory syncytial virus (M2-2)

The M2-2 protein is a small regulatory protein encoded by the human respiratory syncytial virus (RSV). It plays a crucial role in the viral life cycle, acting as a molecular switch to downregulate viral mRNA transcription and promote synthesis of genomic and antigenomic RNA required for virion assembly[2][3][7]. M2-2 also interacts with host proteins, influencing cellular translation and potentially localizing to nuclear sites involved in mRNA splicing[1]. The protein is not an endogenous human molecule or therapeutic target but is instead a viral factor that regulates RSV replication and infection dynamics[2][7]. Note: While M2-2 could be investigated for virus biology or vaccine research, it is not considered a direct therapeutic target, biomarker, or druggable receptor/enzyme/transporter in any known clinical setting[7]. If your question refers to a human regulatory protein, this entry may be based on a mistaken name or context.
