| Type: | Domain | Name: | Extensin domain |
| Description: | Extensins shares protein sequence similarity with hydroxyproline-rich glycoproteins (HRGPs) found in the plant extracellular matrix. They form a structural component which strengthens the primary cell wall; they can account for up to 20% of the dry weight of the cell wall. The key to the role of HRGPs in cell wall self-assembly and cell extension lies in their chemistry, which is dependent on extensive post-translational modifications (PTMs): hydroxylation, glycosylation, and cross-linking. Repetitive peptide motifs characterise HRGPs []. | Short Name: | Extensin_dom |
