Tetraspanins belong to the transmembrane 4 superfamily (TM4SF), and play crucial roles in immune responses. In the present study, a novel tetraspanin gene (designated MmTSPAN) was cloned and characterized from the hard clam Meretrix meretrix. The complete cDNA sequence of MmTSPAN contained an open reading frame (ORF) of 816 bp, which encoded a protein of 271 amino acids. MmTSPAN exhibited highly similarity with previously identified tetraspanins from other species. It contained four transmembrane domains (12-35 aa, 69-92 aa, 99-123 aa and 238-261 aa), characteristic CCG motif and four conservative cysteine residues. The mRNA transcripts of MmTSPAN were ubiquitously detectable in all the tested tissues, with the highest expression level in hepatopancreas. Temporal transcriptional levels in the hepatopancreas revealed significant up-regulation of MmTSPAN by Vibrio splendidus stimulation, with a 3.14-fold increase at 6h compared to the control, and reaching 32.98-fold at 24 h. These results provide useful information for further study of the function of tetraspanin in the innate immune system of M. meretrix, and may offer a new therapeutic target for diseases of M. meretrix.
