Notes:
An anti-Mos protein monoclonal antibody, 4A6, was used to investigate the distribution of the antigen in the epididymis, in which the c-mos gene is reportedly expressed. The 4A6-reactive antigen was found on the basement membrane and luminal surface of the epithelial cells in the caput epididymis of BALB/c male mice as well as in the proximal corpus epididymis, the cauda epididymis, and the vas deferens. The 4A6 antigen was also found on the luminal surface of the epithelial cells in the epididymis of male germ cell-deficient C57BL/6J-Wv/Wv mice. This confirmed that the 4A6 antigen does not derive entirely from the testicular c-Mos protein but is synthesized in the epididymis. Western blot analysis revealed that the molecular weight of the epididymal 4A6 antigen was 50 kDa, which is unusually high for the c-Mos protein. With its specific distribution in the epididymis, the protein should play a specific role in functions of the epididymis. © 1992 Wiley-Liss, Inc.
