CC -!- FUNCTION: Promotes plant cell differentiation, organogenesis and
CC somatic embryogenesis as well as cell proliferation.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- PTM: Sulfation is important for activity and for the binding to a
CC putative membrane receptor. {ECO:0000269|PubMed:9371850}.
CC -!- PTM: PSK-alpha is produced by endopeptidase digestion. PSK-beta is
CC produced from PSK-alpha by exopeptidase digestion.
CC -!- SIMILARITY: Belongs to the phytosulfokine family. {ECO:0000305}.
