May act by recruiting cellulose synthesizing complexes to discrete positions on the cell surface.TISSUE SPECIFICITY:Expressed in roots, stems, leaves, flowers and siliques. Up-regulated in the root zone of rapid longitudinal expansion.MISCELLANEOUS:A partial protein missing the N-terminal signal peptide was reported to complement a yeast mutant defective in phytochelatin synthesis. It is therefore possible that COBRA binds divalent metals.SIMILARITY:Belongs to the COBRA family.SEQUENCE CAUTION:Sequence=BAB10641.1; Type=Erroneous gene model prediction; "
