ESR2（estrogen receptor 2），癌症关联基因，基因ID：2100，该基因编码雌激素受体家族和核受体转录因子超家族中的一员。该基因产物包含一个n端dna结合域和c端配体结合域，定位于细胞核、细胞质和线粒体。在与17β-雌二醇或相关配体结合后，编码的蛋白质形成与特定DNA序列相互作用的同源或异源二聚体以激活转录。某些亚型主要抑制其他雌激素受体家族成员的活性。已经描述了该基因的几个选择性剪接的转录变体，但其中一些变体的全长性质尚未完全描述。[由RefSeq提供，2008年7月]This gene encodes a member of the family of estrogen receptors and superfamily of nuclear receptor transcription factors. The gene product contains an N-terminal DNA binding domain and C-terminal ligand binding domain and is localized to the nucleus， cytoplasm， and mitochondria. Upon binding to 17beta-estradiol or related ligands， the encoded protein forms homo- or hetero-dimers that interact with specific DNA sequences to activate transcription. Some isoforms dominantly inhibit the activity of other estrogen receptor family members. Several alternatively spliced transcript variants of this gene have been described， but the full-length nature of some of these variants has not been fully chara。
