To identify molecules that function in the plant seceretory pathway, we screened for Arabidopsis thaliana cDNA clones that complement the temperature-sensitive (ts), secretion-deficient sec15 mutation of yeast Saccharomyces cerevisiae. RMA1, one of the genes obtained in this screening, suppressed not only the ts growth of sec15 but also its secretory defect. RMA1 is not a structural homologue of SEC15 but encodes a novel 28 kDa protein with a RING finger motif and a C-terminal membraneanchoring domain. Mutational analysis indicates that the RING finger motif of RMA1 is important for its suppression activity. In Arabidopsis plant, RMA1 is ubiquitously expressed. A search for homologous proteins in the database revealed that Arabidopsis, nematode, mouse and human posses close homologues of RMA1.
