ABSTRACT: The nuclear transcription factor E-26-like protein 1 (Elk-1) is thought to impact neuronal differentiation [Sharrocks, A. D. (2001) Nat. Rev. Mol. Cell Biol. 2, 827-837], cell proliferation [Sharrocks, A. D. (2002) Biochem. Soc. Trans. 30, 1-9], tumorigenesis [Chai, Y. L., Chipitsyna, G., Cui, J., Liao, B., Liu, S., Aysola, K., Yezdani, M., Reddy, E. S. P. & Rao, V. N. (2001) Oncogene 20, 1357-1367], and apoptosis [Shao, N., Chai, Y., Cui, J., Wang, N., Aysola, K., Reddy, E. S. P. & Rao, V. N. (1998) Oncogene 17, 527-532]. In addition to its nuclear localization, Elk-1 is found throughout the cytoplasm, including localization in neuronal dendrites [Sgambato, V., Vanhoutte, P., Pages, C., Rogard, M., Hipskind, R., Besson, M. J. & Caboche, J. (1998) J. Neurosci. 18, 214-226], raising the pos
