ABSTRACT
Cytokine-induced suppressor of cytokine signaling (SOCS) family acts as a negative regulator of cytokine receptor signaling to control excessive cytokine effects and inhibit a variety of signal transduction pathways, particularly the Janus kinases/signal transducers and activators of transcription (JAK/STAT) pathway. In present study, SOCS-2 homolog (PfSOCS-2) from pearl oyster Pinctada fucata was cloned and its gene has no intron. Multiple sequence alignments and phylogenetic analysis showed that PfSOCS-2 was clustered with other mollusk SOCS-2. LPS or polyIC challenge and gene expression analysis revealed that PfSOCS-2 involved the innate immune response against bacterial and viral infections and that induction of PfSOCS-2 was varied with the different challenge stimulations. Furthermore, Dual-luciferase reporter assays showed that PfSOCS-2 involved in the regulation of vertebrate target genes containing the IFN-stimulated response element or NF-κB binding site in vitro. These results indicated that SOCS-2 from P. fucata plays a regulatory role against the stimulation.
