Growth rate of bovine skeletal muscle has a major impact on beef yield. Cadherin-11 () was found to be a potential candidate gene for growth and development in beef cattle. This study confirmed the high expression of in bovine using a tissue expression analysis. To understand the transcriptional regulation mechanism of gene, we constructed a double luciferase vector for the promoter region of gene and determined that the core transcriptional regulatory region was located at -129/+55 bp relative to the transcription start site (TSS). In addition, we confirmed that skeletal muscle growth and development-related transcription factor-specific protein 1 (SP1) and glucocorticoid receptor (GR) bind to the gene promoter region at -36/-27 bp and -20/-11 bp, respectively, to regulate expression. These interactions provide valuable information for understanding the mechanism of transcriptional regulation of the bovine gene during muscle growth and development.
牛骨骼肌的生长速度对牛肉产量有重大影响。钙黏蛋白-11（Cadherin-11）被发现是肉牛生长发育的一个潜在候选基因。本研究通过组织表达分析证实了Cadherin-11在牛肌肉中的高表达。为了解Cadherin-11基因的转录调控机制，我们构建了该基因启动子区域的双荧光素酶载体，并确定核心转录调控区域位于相对于转录起始位点（TSS）的-129/+55 bp处。此外，我们证实了与骨骼肌生长发育相关的转录因子特异性蛋白1（SP1）和糖皮质激素受体（GR）分别在-36/-27 bp和-20/-11 bp处与Cadherin-11基因启动子区域结合，以调节Cadherin-11的表达。这些相互作用为理解牛Cadherin-11基因在肌肉生长发育过程中的转录调控机制提供了有价值的信息。
