Abstract Fc receptors (FcRs) are specific to the Fc portion of immunoglobulin (Ig) molecules. Here, four Fc receptor-like proteins, JF-FcR-like protein 1-4, were identified in Japanese flounder. Their open reading frames encoded 358, 255, 519 and 441 amino acid residues, respectively. JF-FcR-like protein mRNAs were mainly detected in kidney and spleen of healthy fish. Injection of formalin-killed cells (FKCs) of Edwardsiella tarda significantly increased the spleen mRNA levels of JF-FcR-like protein 1 but not the other JF-FcR-like proteins. Injection of FKC of Streptococcus iniae did not significantly affect any of the JF-FcR-like protein mRNAs. These findings suggest that the FcR-like proteins have different involvements in pathogen responses. Highlights • Four types of Japanese flounder Fc receptor-like proteins (JF-FcR-like protein 1-4) were identified. • JF-FcR-like protein mRNAs were mainly detected in kidney and spleen. • The mRNA levels of JF-FcR-like protein 1 was increased after Edwardsiella tarda FKC injection.
