CC -!- FUNCTION: Promotes plant cell differentiation, organogenesis and
CC somatic embryogenesis as well as cell proliferation. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- PTM: Sulfation is important for activity and for the binding to a
CC putative membrane receptor. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the phytosulfokine family. {ECO:0000305}.
CC -!- CAUTION: This potential protein codes for a PSK precursor that would
CC produce a PSK-alpha that differs in the last residue (His) from a
CC normal PSK-alpha (Gln). Furthermore there are no ESTs or cDNAs so far
CC for this potential gene. {ECO:0000305}.
