人糖皮质激素受体dna结合因子是糖皮质激素受体转录的抑制因子，与糖皮质激素受体基因（hgr）启动子区相关。从cdna序列推导出的氨基酸序列显示了锌指特征的三个序列基序和一个暗示亮氨酸拉链的基序，其中1个半胱氨酸被发现，而不是所有亮氨酸。GRLF1增强了野生型hGR基因表达的同源下调生化分析表明grlf1的相互作用具有序列特异性，其转录效率是通过与特定序列基序的相互作用来调节的。表达水平由糖皮质激素调节。[由RefSeq提供，2008年7月]
The human glucocorticoid receptor DNA binding factor, which associates with the promoter region of the glucocorticoid receptor gene (hGR gene), is a repressor of glucocorticoid receptor transcription. The amino acid sequence deduced from the cDNA sequences show the presence of three sequence motifs characteristic of a zinc finger and one motif suggestive of a leucine zipper in which 1 cysteine is found instead of all leucines. The GRLF1 enhances the homologous down-regulation of wild-type hGR gene expression. Biochemical analysis suggests that GRLF1 interaction is sequence specific and that transcriptional efficacy of GRLF1 is regulated through its interaction with specific sequence motif. The level of expression is regulated by glucocorticoids. [provided by RefSeq, Jul 2008]
