Humam heat shock protein 90β (HSP90β) is one of several major classes of heat shock proteins in the human lymphocyte. It has special features both in its function and in its gene structure compared with other heat shock proteins. It is rich in the cytoplasm of lymphocyte even at physiological conditions, though it can also be induced by physical stress including elevated temperature. It is now found that HSP90β not only can protect cells to counteract stress,it also plays an important role in many physiological processes shch as growth, development and differentiation of the cell. The gene coding HSP90 β (hsp90β gene) has introns in its DNA sequence...
