Abstract / Description of output

We have identified an abundant 20,000 dalton protein (KAP) by in vitro translation of male mouse kidney mRNA. This protein is synthesized in reduced amounts from female kidney mRNA. A KAP cDNA fragment was purified and used for nucleic acid hybridization studies. Females and castrated males have 10 and 200 fold lower levels, respectively, of KAP mRNA relative to males. The administration of testosterone to females or castrated males results in the induction of KAP mRNA to normal male levels. Testicular feminized (Tfm) mice have 3 fold lower levels of KAP mRNA relative to normal males and are not induced by testosterone. KAP mRNA is not found in significant amounts in tissues other than the kidney, and the KAP gene renatures with kinetics similar to single-copy DNA. With the rapidly expanding knowledge of mouse genetics, KAP should prove useful in determining genetic factors which regulate the inducibility and tissue specificity of a hormonally regulated gene.
