UniProt Comments
Structural component which strengthens the primary cell wall (PubMed:11475326). Forms dendritic structures indicating a propensity for self-assembly through tyrosine cross-linking (PubMed:18256186, PubMed:21415277). Forms intermolecular cross-links exclusively by pulcherosine (three Tyr) (PubMed:18256186). Scaffold formation requires an unobstructed C-terminus of EXT3 (PubMed:18256186). Required for the correct positioning of the cell plate during cytokinesis in cells of the developing embryo (PubMed:12034904). Extensins contain a characteristic repeat of the pentapeptide Ser-Pro4. For this particular extensin, a typical repeat of Ser-Pro3 is found (PubMed:11475326).
