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."
