| Addtional Information | FUNCTION:Promotes plant cell differentiation, organogenesis and somatic embryogenesis as well as cell proliferation.TISSUE SPECIFICITY:Expressed throughout the seedling. More abundant in fragments containing shoot or root apexes where cells proliferate vigorously.PTM:Sulfation is important for activity and for the binding to a putative membrane receptor.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. |
