DESCRIPTION

Also known as SERK1_ARATH, SERK1. Dual specificity kinase acting on both serine/threonine- and tyrosine-containing substrates. Phosphorylates BRI1 on 'Ser-887' and CDC48 on at least one threonine residue and on 'Ser-41'. Confers embryogenic competence. Acts redundantly with SERK2 as a control point for sporophytic development controlling male gametophyte production. Involved in the brassinolide signaling pathway. Probably required during small peptide (e.g. RGF1) signaling (Probable). Involved in the perception of phytosulfokine and subsequent signal transduction (PubMed:26308901). Acts as a RLK5 coreceptor and promotes high-affinity IDA sensing, thus being a positive regulator of floral abscission (PubMed:27058169). Monomer, homo- and heterodimer. Interacts with KAPP, CDC48A, GRF6 or GRF7, SERK2, BRI1 and SERK3/BAK1 to form the SERK1 signaling complex. Bind to BRI1 in a brassinolide-dependent manner (PubMed:23929946). Heterodimer with PSKR1 (PubMed:26308901). Interacts with the EF-Tu receptor EFR and FLS2 in a specific ligand-induced manner. Interacts with ERECTA in a EPF2-induced manner. Interacts with ERL1 in a EPF1-induced manner. Interacts with TMM (PubMed:26320950). In the presence of the signal peptide RGF1, interacts with RGI1/RGFR4/RCH2, RGI2/RGFR3/RCH1, RGI3/RGFR1, RGI4/RGFR2/SKM2 and RGI5/RGFR5 (PubMed:27229311).
