DESCRIPTION

Also known as PSKR1_ARATH, PSKR1, PSKR. 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). Homo- and heterodimers with PSY1R (PubMed:25267325). Heterodimers with the somatic embryogenesis receptor-like kinases (SERKs) (PubMed:26308901). PSK is not directly involved in PSKR-SERK interaction but stabilizes PSKR island domain for recruitment of a SERK (PubMed:26308901). Part of a functional complex containing PSKR1, BAK1, CNGC17, and AHA (PubMed:26071421). Interacts with AHA1, AHA2, and BAK1, but not with CNGC17 or BRI1 (PubMed:26071421).
