Protein
Somatic embryogenesis receptor kinase 1
Organism
Arabidopsis thaliana
Function
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.
Similarity
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
