A conserved dibasic site is essential for correct processing of the peptide hormone AtRALF1 in Arabidopsis thaliana.

FEBS letters - 15 Oct 2008

Abstract excerpt

Prohormone proteins in animals and yeast are typically processed at dibasic sites by convertases. Propeptide hormones are also found in plants but little is known about processing. We show for the first time that a dibasic site upstream of a plant peptide hormone, AtRALF1, is essential for processing. Overexpression of preproAtRALF1 causes semi-dwarfism whereas overexpression of preproAtRALF1(R69A), the...
