Viral proteins are proteins encoded by viruses that play various essential roles in the viral replication cycle and interaction with host cells. These proteins are involved in processes such as viral entry and attachment to host cells, genome replication and transcription, assembly and release of new viral particles, and modulation of host immune responses. Understanding viral proteins is crucial for developing antiviral drugs and vaccines to combat viral infections. Researchers study viral proteins to uncover their functions, structures, and interactions with host molecules in order to better understand viral pathogenesis and develop new strategies for treating viral diseases.
