Functional Description
Protein disulfide isomerase that associates with RD21A protease for trafficking from the ER through the Golgi to lytic and protein storage vacuoles of endothelial cells in developing seeds. Regulates the timing of programmed cell death (PCD) of the endothelial cells by chaperoning and inhibiting cysteine proteases during their trafficking to vacuoles.
