SpgC1qR interacts with WSSV VP28 exhibiting antiviral activity.

ABSTRACT: Although human gC1qR is a multi-ligand binding protein with diverse biological functions, the functions of invertebrate gC1qR homologues remain largely unknown. In the present study, we characterized a novel gC1qR homologue, namely SpgC1qR, from mud crab Scylla paramamosain. SpgC1qR shared high identity and similar three-dimensional structure with human gC1qR. After challenge with White spot syndrome virus (WSSV), the transcripts of SpgC1qR were significantly increased, suggesting that SpgC1qR may be involved in antiviral immune response. To reveal the likely antiviral activity of SpgC1qR, the proliferation profile of WSSV in SpgC1qR-silenced crabs was examined. The result showed that knockdown of SpgC1qR by RNAi facilitated viral pro
