CC -!- FUNCTION: Structural component which strengthens the primary cell wall.
CC -!- SUBCELLULAR LOCATION: Secreted, primary cell wall.
CC -!- TISSUE SPECIFICITY: Predominantly expressed in the roots.
CC -!- DEVELOPMENTAL STAGE: Early expressed in the whole plant, but was
CC restricted to lower stems, flower buds and roots in the mature plant (6
CC weeks old).
CC -!- INDUCTION: By wounding and water stress; in response to plant hormones
CC 2,4-D, BAP treatment; in response to L-Pro treatment. Repressed by salt
CC stress.
CC -!- PTM: Extensins contain a characteristic repeat of the pentapeptide Ser-
CC Pro(4). The proline residues are hydroxylated and then O-glycosylated
CC (arabinosylation).
CC -!- PTM: Synthetised as soluble proteins which become insolubilised in the
CC cell wall through the intermolecular cross-linking of Tyr on adjacent
CC monomers. Isodityrosine (IDT) stabilizes and makes rigid the part of
CC the polypeptide where IDT functional sites are present.
CC -!- SIMILARITY: Belongs to the extensin family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AEE79253.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
CC Sequence=BAB21544.1; Type=Frameshift; Evidence={ECO:0000305};
CC Sequence=BAB21544.1; Type=Miscellaneous discrepancy; Note=Incomplete cDNA clone.; Evidence={ECO:0000305};
