To investigate the immunological function of TRIM13 in zebrafish (Danio rerio), we cloned the zebrafish TRIM13 homolog (DrTRIM13) and obtained its complete coding sequence (CDS) and3'-untranslated region (3'-UTR) through sequencing and sequence assembly. Reverse transcription PCR was used to examine the tissue distribution of DrTRIM13. Additionally, fluorescence microscopy was performed to visualize protein localization. Our results demonstrate that the cloned DrTRIM13 cDNA consists of a 276-bp 3'-UTR and a 1215-bp open reading frame (ORF), encoding a 404-amino acid protein. Phylogenetic analysis indicated that DrTRIM13 shares the highest homology and closest evolutionary relationship with carp (Cyprinus carpio). Subcellular localization in HeLa cells confirmed predominant cytoplasmic distribution. These findings provide a theoretical framework for mitigating viral diseases in aquaculture.
