CC -!- FUNCTION: Modulates cell morphogenesis by regulating cell wall
CC formation and assembly, and/or growth polarization. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted, cell wall {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed in flowers, stamen, pollen, and
CC pollinated carpels (at protein level). {ECO:0000269|PubMed:12644681}.
CC -!- PTM: Hydroxylated on proline residues in the S-P-P-P-P repeat.
CC {ECO:0000250}.
CC -!- PTM: O-glycosylated on hydroxyprolines. {ECO:0000250}.
