| Addtional Information | FUNCTION:Promotes plant cell differentiation, organogenesis and somatic embryogenesis as well as cell proliferation (By similarity).PTM:Sulfation is important for activity and for the binding to a putative membrane receptor (By similarity).SIMILARITY:Belongs to the phytosulfokine family.CAUTION:This potential protein encodes for a PSK precursor that would produce a PSK-alpha that differs in the last residue (His) from a normal PSK-alpha (Gln). Furthermore there are no ESTs or cDNAs so far for this potential gene. |
