We provide the IFN-伪 gene sequence of Red-crowned Crane for the first time.
The crIFN-伪 expressed in E. coli could inhibit the replication of VSV on CEF.
The antiviral activities were abrogated by rabbit anti-crIFN-伪 antibodies in vitro.
CrIFN-伪 could be expressed in CEF and was mainly located in the cytoplasm.
