Addtional InformationFUNCTION:Structural component which strengthens the primary cell wall.TISSUE SPECIFICITY:Predominantly expressed in the roots.DEVELOPMENTAL STAGE:Early expressed in the whole plant, but was restricted to lower stems, flower buds and roots in the mature plant (6 weeks old).INDUCTION:By wounding, water and cold stresses; in response to plant hormones 2,4-D, BAP, GA3, and ABA treatment; in response to L-Ser, Hyp and L-Pro treatment. Slightly repressed by salt stress.PTM:Extensins contain a characteristic repeat of the pentapeptide Ser-Pro(4). For this particular extensin, a typical repeat of Ser- Pro(3) is found. In both cases, the proline residues are hydroxylated and then O-glycosylated (arabinosylation).PTM:Synthetised as soluble proteins which become insolubilised in the cell wall through the intermolecular cross-linking of Tyr on adjacent monomers. Isodityrosine (IDT) stabilizes and makes rigid the part of the polypeptide where IDT functional sites are present.SIMILARITY:Belongs to the extensin family.SEQUENCE CAUTION:Sequence=BAB20084.1; Type=Miscellaneous discrepancy; Note=Chimeric cDNA. Its C-terminal part is derived from the gene At2g20230; Sequence=BAB20086.1; Type=Miscellaneous discrepancy; Note=Truncated cDNA resulting of the removal of two cryptic introns in the genomic sequence;
