The function of PmCBP in viral infection was determined when it was found to directly interact with WSSV067 (encoding the WSSV envelope protein VP53A) [109] and other envelope proteins (including VP24, VP53A, VP110, VP53B, VP337, VP32, VP124, VP41A, VP51B, VP60A and VP39B) of WSSV [23]. The gene discussed is ERVW-1; the disease is viral infectious disease.
