| Protein description | ORF6 encodes a viral accessory protein. Based on its similarity to other coronavirus proteins, ORF6 protein is thought to play a role in viral pathogenesis.The functions of orf6 are as follows: 1) it binds the nsp8 in the replication\transcription complex which reflects its importance for the viral replication, 2) it increases the infection titer, 3) it contributes to the evasion of the virus to the host immune system through inhibition of the interferon induction and signaling pathway; it inhibits the Signal Transduction and Activator of Transcription (STAT 1), and 4) it participates in the formation of the DMV in the host cells which helps in protein trafficking to ensure the assembling of the virus. |
