Characterisation of the differentially regulated trout protein 1 (DRTP1) gene in rainbow trout (Oncorhynchus mykiss)
Journal article Increased levels of differentially regulated trout protein 1 (DRTP1) mRNA transcripts have been reported in fish after activation of the acute phase response. While the function of the DRTP1 protein still remains to be elucidated, this study focused on the genomic organisation of the...

While the function of the DRTP1 protein still remains to be elucidated, this study focused on the genomic organisation of the gene, the quantification of the DRTP1 transcript in various tissues, and the isolation and analysis of the 5' regulatory region of the DRTP1 gene in rainbow trout (Oncorhynchus mykiss).
