General annotation (Comments)

Function

Promotes plant cell differentiation, organogenesis and somatic embryogenesis as well as cell proliferation.

Subcellular location

Secreted.

Tissue specificity

Expressed throughout the seedling. More abundant in fragments containing shoot or root apexes where cells proliferate vigorously.

Post-translational modification

Sulfation is important for activity and for the binding to a putative membrane receptor.

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.

Sequence similarities

Belongs to the phytosulfokine family.
