| pubmed-article:3197833 | pubmed:abstractText | Mouse lymphoma cells contain a nonactivated glucocorticoid receptor of Mr approximately 330,000 which is heteromeric in nature and is unable to bind to DNA. Following affinity labeling of the steroid-binding subunit and subsequent cross-linking with dimethyl suberimidate at various times either in cell extracts or in intact cells, a series of labeled bands was detected in SDS gels. From the molecular masses of completely and partially cross-linked complexes we conclude that the large nonactivated receptor is a tetramer composed of two 90 kDa subunits, one 50 kDa polypeptide and one steroid-binding subunit. | lld:pubmed |
