UniProtKB - Q9ZVR7 (PSKR1_ARATH)
Protein
Phytosulfokine receptor 1
Gene
PSKR1
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Functioni
Phytosulfokine receptor with both a serine/threonine-protein kinase activity and a guanylate cyclase activity (PubMed:21504901). Regulates, in response to phytosulfokine binding, a signaling cascade involved in plant cell differentiation, organogenesis, somatic embryogenesis, cellular proliferation and plant growth. Involved in plant immunity, with antagonistic effects on bacterial and fungal resistances (PubMed:23062058). Not involved in PSY perception. CNGC17 and AHAs form a functional cation-translocating unit that is activated by PSKR1/BAK1 and possibly other BAK1/RLK complexes (PubMed:26071421).4 Publications
Miscellaneous
PSKR1 and PSYR1 mediate a signaling pathway by two distinct ligands, which redundantly contribute to cellular proliferation and plant growth.1 Publication
Catalytic activityi
Cofactori
Activity regulationi
cGMP suppresses kinase activity.1 Publication
Kineticsi
- KM=7.5 µM for Ser/Thr peptide 1 for the protein serine-threonine kinase activity1 Publication
- Vmax=1800 nmol/min/mg enzyme with Ser/Thr peptide 1 as substrate1 Publication
