Description
Summary:Muscle formation directly determines meat production and quality. The non-SMC condensin I complex subunit G (NCAPG) is strongly linked to the growth features of domestic animals because it is essential in controlling muscle growth and development. This study aims to elucidate the tissue expression level of the bovine <i>NCAPG</i> gene, and determine the key transcription factors for regulating the bovine <i>NCAPG</i> gene. In this study, we observed that the bovine <i>NCAPG</i> gene exhibited high expression levels in longissimus dorsi and spleen tissues. Subsequently, we cloned and characterized the promoter region of the bovine <i>NCAPG</i> gene, consisting of a 2039 bp sequence, through constructing the deletion fragment double-luciferase reporter vector and site-directed mutation-identifying core promoter region with its key transcription factor binding site. In addition, the key transcription factors of the core promoter sequence of the bovine <i>NCAPG</i> gene were analyzed and predicted using online software. Furthermore, by integrating overexpression experiments and the electrophoretic mobility shift assay (EMSA), we have shown that cAMP response element binding protein 1 (CREB1) and myogenic differentiation 1 (MYOD1) bind to the core promoter region (−598/+87), activating transcription activity in the bovine <i>NCAPG</i> gene. In conclusion, these findings shed important light on the regulatory network mechanism that underlies the expression of the <i>NCAPG</i> gene throughout the development of the muscles in beef cattle.
