Comparative immunochemical and structural similarities of five stress proteins from various tissue types.
1. Incorporation of radioactive phosphate or leucine by stress proteins from rodent lymphoma, submaxillary and liver nuclei were observed in two-dimensional gels following chemical and environmental stress. 2. The stress proteins were isolated from second-dimension gels and their similarities compared. Mol. wt determinations, immunochemical blotting and protease V8 peptide mapping confirmed the identical nature of the stress proteins possessing identical Mr, but from diverse tissue types. 3. These data imply that highly similar stress proteins exist in diverse tissues, are conserved during evolution, and possess some elemental and essential function.
