UniProtKB - A3EX97 (ORF4B_BCHK4)
Protein
Non-structural protein ORF4b
Gene
ORF4b
Organism
Bat coronavirus HKU4 (BtCoV) (BtCoV/HKU4/2004)
Status
Functioni
Plays a role in the inhibition of host innate immunity by inhibiting the interaction between host IKBKE and MAVS. In turn, this inhibition prevents the production of host interferon beta. Additionally, may also interfere with host antiviral response within the nucleus.1 Publication
