Abstract
Major histocompatibility complex (MHC) genes are essential for distinguishing between individuals in all jawed vertebrates. Although MHC class I (mhc1) genes in zebrafish comprise distinct haplotypes, not all members of the mhc1 gene family have been fully characterized. In this study, we report the identification of two novel U lineage genes isolated from the WIK strain of zebrafish. These new mhc1 genes, named una and uoa, are located in tandem on chromosome 19 with > 70% homology to previously isolated U genes. Sequencing of their neighboring genes revealed that una and uoa form a unique haplotype different from the previously known U lineage haplotypes. Additionally, we determined the expression profiles of U, Z, and L genes in three different tissues. These findings collectively suggest that mhc1 U lineage genes and their haplotypes in zebrafish are more divergent than previously considered, and their expression patterns vary significantly among different tissues.
