ERVW-1 and infection: There were several reports about WSSV attachment proteins or candidate receptors in shrimp, such as Penaeus monodon Rab7 binding to WSSV envelope protein VP28, which is beneficial for WSSV infection [32], and a chitin-binding protein (CBP) in P. monodon interacts with 11 WSSV envelope proteins, which can reduce and delay mortality upon WSSV challenge in the neutralization assay [33,34].
