Abstract: The aim of this study was to investigate the effects of myosin light chain 3 (MLC1v or MYL3) on the regulation of skeletal muscle transcription, and to identify its functional relationship with muscle growth and development. MYL3 gene was cloned and its biological structure was analyzed by bioinformatics method. The expression of MYL3 gene in different tissues and at different stages was studied by means of fluorescence quantitative PCR technique. Immunohistochemistry showed that the expression locus of MYL3 gene were in the dorsal longissimus muscle. Western Blotting was used to study the expression of MYL3 in different tissues and at different stages. The results showed that the MYL3 gene of Black cattle (sequence number:NM_001076501.2) was cloned with a full-length reading frame of 600 bp, encoding 199 amino acids. Phylogenetic tree analysis showed that its homology was higher. Gene expression analysis showed the highest expression in the heart, followed by the longissimus muscle, and little in other tissues. The expression of MYL3 gene increased with the increase of age. The MYL3 protein mainly expressed in the myofilament of skeletal myofibrils, and increased with the age of the month at different stages. Presumably MYL3 might play an important role in skeletal muscle growth and development.

Key words: MYL3, Black cattle, Luxi cattle, Longissimus muscle
