CC   -!- FUNCTION: Anther-specific cell wall protein which could contribute to
CC       the cell wall architecture of epidermal anther cells via intermolecular
CC       disulfide bridges.
CC   -!- SUBCELLULAR LOCATION: Secreted, cell wall.
CC   -!- TISSUE SPECIFICITY: Epidermal anther cells.
CC   -!- DEVELOPMENTAL STAGE: Late developmental stages.
