PARP14 and infection: Both duck PARP14 genes also have a predicted RNA binding domain, which is not present in the human PARP14. PARP14.1 (LOC101789908) is upregulated by both BC500 and VN1203 infection in ducks, while PARP14.2 (LOC101798744) is only upregulated by VN1203 in lungs and spleens of infected ducks.
