An LRR-only protein gene was cloned from scallop Chlamys farreri.
Its mRNA transcripts in haemocytes increased after PAMP stimulations.
CfLRRop-1 exhibited binding activity to various PAMPs.
The mRNA expression level of CfLRRop-1 was up-regulated when CfTLR was suppressed.
CfLRRop-1 induced release of TNF-伪 from mixed primary cultured scallop haemocytes.
