CC -!- FUNCTION: Promotes plant cell differentiation, organogenesis and
CC somatic embryogenesis as well as cell proliferation.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- TISSUE SPECIFICITY: Expressed throughout the seedling. More abundant in
CC fragments containing shoot or root apexes where cells proliferate
CC vigorously.
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 -!- MISCELLANEOUS: The N-terminal tripeptide (YIY) is the active core.
CC -!- SIMILARITY: Belongs to the phytosulfokine family. {ECO:0000305}.
