CC   -!- FUNCTION: Structural component in primary cell wall.
CC   -!- SUBCELLULAR LOCATION: Secreted, primary cell wall.
CC   -!- PTM: Hydroxylated on proline residues in the S-P-P-P-P repeat.
CC   -!- PTM: O-glycosylated on hydroxyprolines.
CC   -!- CAUTION: It is uncertain whether Met-1 or Met-10 is the initiator.
