To understand the physiological functions of the 105‐kDa protein which is testis‐specific and HSP90 (90‐kDa heat‐shock protein) related protein. the appearance of it in the testis has been followed during the development of rat. On immunoblotting analysis. the 105‐kDa protein did not appear until after the age of five weeks, while HSP90 could be detected at three weeks. In the spermatozoa. the 105‐kDa protein was much abundant but not in the LC‐540 cells (a cell line from Leydig cell tumor in rat testis) cytosol. This finding has attracted much attention to the relationship between this protein and sperm functions.
