SERK1, Somatic embryogenesis receptor kinase 1
Enzyme Classification 126.96.36.199
Also Known as
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. Monomer, homo- and heterodimer. Interacts with KAPP, CDC48A, GRF6 or GRF7, SERK2, BRI1 and SERK3/BAK1 to form the SERK1 signaling complex. 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).
