UniProt annotation for PSKR1_ARATH » Phytosulfokine receptor 1
FUNCTION: Phytosulfokine receptor with a serine/threonine-protein kinase activity. Regulates, in response to phytosulfokine binding, a signaling cascade involved in plant cell differentiation, organogenesis, somatic embryogenesis, cellular proliferation and plant growth. Not involved in PSY perception.

CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein.

TISSUE SPECIFICITY: Weakly expressed in roots, leaves, stems and flowers.

INDUCTION: Up-regulated by fungal infection and wounding.

MISCELLANEOUS: PSKR1 and PSYR1 mediate a signaling pathway by two distinct ligands, which redundantly contribute to cellular proliferation and plant growth.
