krox 20 is an inducible immediate early response gene. To determine if krox 20 has a physiological role in the adult central nervous system (CNS), this study sought to demonstrate the presence of krox 20 in adult rat brain. RNA analysis showed the presence of krox 20 transcripts in the CNS, including the cortex. Polyclonal antibodies to a Krox 20 fusion protein demonstrated 79 and 55 kDa antigens in nuclear CNS homogenates. Neither RNA nor protein analysis was able to demonstrate an induction of krox 20 by a seizure at times when other immediate early response genes are known to be induced. Immunohistochemical analysis revealed staining at several levels throughout the nervous system. This staining was predominantly nuclear, consistent with the role of krox 20 as a transcription factor. These data show that krox 20 is present in the adult CNS, yet differs in response to stimuli as compared to other related transcription factors with a zinc finger motif, such as NGFI-A and NGFI-C.
