| Abstract: | Highly purified activated cytoplasmic glucocorticoid hormone receptor binds with high affinity to sites in the nuclear envelope. Nuclear envelope fragments can be isolated from purified chromatin. They bind activated cytoplasmic glucocorticoid receptor with the same equilibrium constant as nuclear envelopes. The presence of envelope components in chromatin is confirmed by the virtual identity of the gel electrophoretic glycoprotein pattern of nuclear envelope, chromatin nonhistones, and nuclear envelope fragments from chromatin. |
