This study explores the genomic structure of a zebrafish gene located on chromosome 15, focusing on its signal peptide, transmembrane domains, and the associated protein sequences. The analysis highlights consensus sequences within the V-type immunoglobulin domain and the presence of an intracytoplasmic C-terminal tail. We present detailed sequence data, including fundamental elements of gene expression and regulation, which may elucidate the functional characteristics of this gene in zebrafish.
