Three classes of nuclear import signals bind to plant nuclei

Plant Physiol. 1995 Apr;107(4):1055-8. doi: 10.1104/pp.107.4.1055.

Abstract

Three nuclear localization signals (NLS), including an unusual Mat alpha 2-like NLS from maize (Zea mays) R, were found to compete for binding to plant nuclei. In addition, the authentic yeast Mat alpha 2 NLS, which does not function in mammals, was shown to function in plants in vivo. Our results indicate that plants possess a site at the nuclear pore complex that recognizes the three known classes of NLSs.
