| Addtional Information | FUNCTION:Promotes plant cell differentiation, organogenesis and somatic embryogenesis as well as cell proliferation.INDUCTION:Expression is regulated by a signal transduction pathway activated by auxin and cytokinin.PTM:Sulfation is important for activity and for the binding to a putative membrane receptor. Deletion of the sulfate groups of Tyr- 67 and Tyr-69 resulted in compounds with respectively 0.6% and 4% of the activity.PTM:PSK-alpha is produced by endopeptidase digestion. PSK-beta is produced from PSK-alpha by exopeptidase digestion.MISCELLANEOUS:The N-terminal tripeptide (YIY) is the active core.SIMILARITY:Belongs to the phytosulfokine family. |
