Abstract:

The aim of this study was to understand the structure and function of ferritin light chain(FTL)gene in yak and its expression pattern in eight tissues of different age groups.The coding sequence(CDS)of FTL gene was cloned from the cDNA of liver tissue of adult(36 months old)Meiren yak,and bioinformatics analysis was carried out.The relative expression of FTL gene in heart,liver,spleen,lung,kidney,longissimus dorsi,fat and testis was detected by Real-time fluorescence quantitative(qRT-PCR).The results showed that the CDS region of FTL gene of Meiren yak was 528 bp,encoding 175 amino acids,and had the closest relationship with wild yak and cattle(99.8%).FTL protein was a stable hydrophilic secretory protein without signal peptide and transmembrane structure.It was mainly distributed in the cytoplasm.The secondary structure of the protein was mainly α-helix,which mainly interacted with FTH1,SCARA5,NCOA4 and other proteins.The results of qRT-PCR showed that the expression levels of FTL gene in adult cattle were liver,kidney,testis,spleen,lung,fat,longissimus dorsi and heart,respectively.The expression levels of FTL gene in fat and longissimus dorsi tissues of 7-day-old calves were the highest,and the expression level of FTL gene in liver tissue of adult cattle was the highest.By comparing the two stages,it was found that the expression levels of fat,longissimus dorsi and heart tissues decreased with the increase of age,while the expression levels of lung,spleen,testis,kidney and liver tissues increased with age.
