THE PROTEIN COMPOSITION OF NUCLEAR MATRIX IN CELLS OF DIFFERENT ANIMAL TISSUES
Summary
The protein composition of nuclear matrix preparations, isolated from different animal tissues under the same conditions, possesses species and tissue specificity. The preparations of nuclear matrix are resistant to additional treatments with dissociating agents (EDTA, NaCl, urea), but their incubation in the presence of thiols results in dissociation of some proteins, that confirms the assumption on participation of disulfide intersubunit bonds in organization of skeletal structures of interphase nucleus.
