Abstract

C-type lectin receptors (CTLR) are cell-surface signalling molecules that recognize a range of highly conserved pathogen molecules and instigate the appropriate immune response. Here, we report the cloning, sequencing, mapping and expression pattern of the bovine C-type lectin domain family 7, member A (CLEC7A; synonyms CLCSF12, Dectin-1). We identified two isoforms, similar to the human system, with a long and short neck. Overall, the organization of the two bovine CLEC7A genes is similar to that of humans and mice. The CLEC7A gene maps on Bos taurus chromosome 5 (BTA5). mRNA transcripts for CLEC7A were detected in bone-marrow cells, monocytes, macrophages and dendritic cells and NK cells, but not in CD4(+) T-cells or CD21(+) B-cells. The increased knowledge of the genomic organization of the bovine CTLR genes may promote our understanding of their evolution and help in the identification of bovine genes underlying disease-resistance traits.
