1α,25(OH)_2D_3受体存在于细胞核内,用0.3M以上的强碱性缓冲液可以从细胞核内溶出,激素-受体复合物和DNA有很高的亲合力。因此考虑1α,25(OH)_2D_3受体和类固醇激素受体可能很相似。但
1α, 25 (OH) _2D_3 receptors exist in the nucleus and can be eluted from the nucleus with 0.3 M or more strong alkaline buffer. The hormone-receptor complex has high affinity with DNA. Therefore consider the 1α, 25 (OH) _2D_3 receptors and steroid hormone receptors may be very similar. but
